FIG WALNUT SUNDAE. A large cone of ice cream is placed on a plate or sundae dish. A liberal spoonful of chopped figs is scattered over the ice cream, and another of chopped walnuts. Cover well with rich whipped cream and top with a creme de menthe cherry. Served daintily, it looks fine, tastes good, and will make a winner.

CONTROLLING THE COLD TASTE OF ICE

CREAM.
A principle of physics controls the cold taste of ice

If an ice-cream manufacturer wishes to have his ice cream taste cold a long time he can do so by making simple changes in the cream mixture he freezes, the actual temperature of the frozen cream having little to do with it. The scheme has been worked out by chemists of the Iowa State College.

The scientific principle, according to the Pacific Drug Review, is that of specific heat. The specific heat of an article is the intensity of heat needed to raise its temperature a given number of degrees, or, in effect, the rapidity with which the article takes up heat. Water is taken as the standard, and scientists know the specific heat of most substances compared with water. These chemists carefully worked out the specific heat of milk, cream, and various other dairy products, discovering that pure cream has a low specific heat and that fatty substances do not take up heat so quickly and effectively as does water.

This explains why sherbets and other ices taste so cold when they first reach the mouth, but do not give the cold taste long. They have a high specific heat and quickly take up heat from the mouth, then melt.

With ice cream the more fat there is in the formula the lower the specific heat. Accordingly a very fat cream will not taste disagreeably cold at first, but a spoonful of ice cream in the mouth will maintain its cold taste longer. Thus the cold taste can be controlled by the amount of fat used.

CHOCOLATE POPCORN SUNDAE. The usual cone-shape measure of chocolate ice cream. Use well-popped corn from which all the hard unpopped kernels have been removed. Sprinkle this very liberally over the ice cream, dressing down with a spoon so that the popcorn will stick to the sides and top of the ice cream. Cover with an ounce of very heavy hot chocolate sauce. Top the whole with a large spoonful of whipped cream. You will find few sundaes that will look, taste or sell better than this one.

KALEIDOSCOPE SUNDAE. Place a small disherful of chocolate ice cream and the same quantity oi vanilla ice cream in a sundae cup. Upon the chocolate ice cream put half a ladleful of caramel dressing with a chopped pistachio nut and a whole green cherry. Upon the vanilla ice cream put a half ladleful of marshmallow dressing and decorate with cocoanut and one red cherry. Place a lady.finger between the two parti-colored mounds.

STRAWBERRY SHERBET SUNDAE. Get a box of fresh strawberries. Hull and cut the berries in half and place in a fruit bowl. Squeeze the juice of two oranges into another bowl. To this juice add one-half pound of granulated sugar. Pour over the fresh strawberries and stir all together until the sugar is dissolved. In the usual sundae dish place a measure of ice cream, Over the ice cream pour a ladleful of orange-strawberries and top with whipped cream. This has a novel flavor and is very pleasant and successful.

SUPERBA PUNCH. Lemon syrup, one pint; strawberry syrup, onė pint; orange syrup, one pint; solution acid phosphate, one and one-half ounces; one orange, sliced. Put into a punch bowl. To dispense, put one and one-half ounces into a mineral water glass and fill with carbonated water. Top off with a maraschino cherry and serve with a straw.

CREME DE MENTHE CREAM SUNDAE. Strip the leaves from two dozen good stalks of mint. Chop the leaves fine and rub them to a pulp with one-half pound granulated sugar, add a little water, and heat until the sugar is dissolved. Stir this well and add two or three drops of vegetable green color and the juice of a lemon.

Pour an ounce of this mint syrup over a ten-to-quart cone dipper of ice cream. Sprinkle with chopped black walnut meats and cover with whipped creain. This makes a very tasty dish and quite a novelty.

SEPTEMBER EVE. Strawberries, crushed. 1 tablespoonful; raspberries, 1 table. spoonful; pineapple, crushed, ] tablespoonful;

grape juice syrup, 1% fluidounces; vanilla extract, dash; milk, 1 fluidounce; ice cream, 1 tablespoonful; crushed ice, enough.

Shake well and fill the glass with fine stream from fountain. Serve with a spoon.

CARAMEL NUT SUNDAE. Chop together equal parts of pecans, English and black Walnuts and pistachio nuts. Mix with heavy caramel syrup. Pour enough of this dressing over a small disherful of vanilla

TENDENCY TOWARD SHORT FOUNTAINS.

An interesting development in the manufacture and sale of soda fountains, according to the Canadian Pharmaceutical Journal, is said to be the decreased demand for long fountains. More small fountains are being sold than ever before, and this tendency is likely to become more pronounced.

There are reasons back of this development, one in particular being the fact that the best customers of the soda fountain manufacturers are the drug store, which because of lack of floor space, prefer the short fountains. Confectionery stores and department stores have been the principal purchasers of the large fountains.

The drug store is preëminently the distributor of soda water and ice cream. The public appreciates the convenience, the cleanliness and the quick service of the average drug store. There is an intelligence found

BUSINESS HINTS

in drug stores as a rule in catering to the best class of trade that is not always to be found in stores operated by those who do not keep pace with public demand in such things. It is the opinion of many who are in close touch with the trade every business day of their lives that the drug store is coming more and more to the front for the excellence of its soda fountain service. Some of the drug stores have set an example in this respect that has lifted the dispensing of soda water to a plane that leaves no place for the fountain where service and quality are not the key-notes.

The Bulletin of Pharmacy as an Ad-writing Aid.

Halls & Dolson, proprietors of the Owl Drug Store, Nogales, Arizona, run advertisements in their local paper twice a week. The ads take the form of short, snappy paragraphs and are run in a column of the paper headed, “The Owl Says.” A reproduction of an owl adorns a space in the upper left-hand corner of the first paragraph of the column.

Material for the advertising paragraphs is obtained, according to Mr. Dolson, as follows: "We read the BULLETIN OF PHARMACY and get many good ideas from it. After reading the various articles we adapt the ideas to suit our needs and use them in newspaper ads twice a week. Here are a few of the paragraphs so obtained which have been used recently:"

LEMON JUICE THAT WILL KEEP. It is not at all times convenient or inexpensive to secure good lemons; when, however, it is, here is a way, described by the Confectioners' Gazette, which will enable the druggist to prepare the juice for future use:

Strain any convenient quantity of expressed juice through a cloth and then mix the liquid with about onefourth its volume of powdered talc and shake for about 15 minutes. Then place aside for half an hour. Next shake again for a few minutes and once more let stand, after which filter through paper, add ten per cent of sugar to the filtrate and bring to a boil.

During this time place the bottles to receive the juice in a kettle of water, fill them with water and boil them in the kettle. Empty the bottles, pour in the boiling lemon juice as quickly as possible and close up at once with a good cork previously dipped into paraffin. Juice prepared in this manner is said to possess unlimited keeping qualities.

HOW TO WHIP CREAM. Cream to whip readily should be of moderate richness and not too fresh. The average milkman's cream is too thin, the cream sold in small jars in the city too thick. By diluting the thick cream with nearly an equal amount of milk you will have it right. Have the cream cold and turn it into a large cold mixing bowl. Surround the bowl with ice water. Beat with a wire whip such as bakers use and whip until thick. Try to lift the cream upward as you beat, but not with a stirring motion. When thick enough add powdered sugar and vanilla extract.-Pacific Drug Review'.

If the milk is pure, some will adhere to the needle; but if water has been added, even in small proportions, it will come forth quite clean.

Plain Language for Ads.

The wisdom of using plain every-day language when composing "copy" for newspaper ads is well brought out in the following extract, taken from an address delivered by George L. Munn, of Springfield, afterward allowed, was there a gain or loss, and how much?”

Give this problem to almost any group of people, with the possible exception of a few merchants making frequent discounts, and half of your people will immediately say that there is neither a gain nor a loss. Of the remainder who may suspect that some change has taken place, few will be able to say offhand that there has been a loss.

This is due almost wholly to the failure to grasp the idea that the rate of per cent represents a fractional part of the base, and that in problems such as the one just given, there are two distinct bases, the second being 40 per cent greater than the first, and that, therefore, the second percentage will be 40 per cent greater than the first, thus making the discount 40 per cent, or 16 per cent of the original cost.

It is necessary to get the idea that there is no equality between rates of per cent unless their bases are equal, and, furthermore, that no comparison can be made between them until they have been reduced to terms of the same unit value or to per cents of the same base.

The mention of any number of per cent is meaningless unless we couple with it a specification of our basis of computation.

Mass., before the Massachusetts Retail Jewelers' Association and printed in the Keystone Weekly:

"Isn't it wonderful how differently we talk when we push a pencil instead of wag a tongue? Remember the preacher whose sermon on 'The Personal Devil inade a big hit because he was so 'full of his subject?' A series of the best advertisments I ever saw were written by an old furniture dealer who in desperation sat down and put on paper the very things he said to customers: 'That set is genuine 'way through. Its joints are all dovetailed. That's where the two pieces of wood sort of grip each other, like shaking hands. No glue in that, 'tain't needed. And they won't fall all to pieces when they're hitched that way. You'll pay a few dollars more for a set like that, but you'll hand it over to your great grandchildren some day, and it will be just as good as new.' He was talking honestly, in his own honest style, about honest goods, and he did business.

"The unhappy ad-smith who wrote, 'If you want to have a fit wear our shoes,' wasn't careful to write as he talked. He would never have said that to a customer. Words must be treated as fairly as show-windows. You can't dump any old mouthful of words into an ad, or any old armful of goods into a window and get results. The world is pretty simple-minded after all. Lincoln got himself understood because he stuck to the plain and limited language of plain folks, and we are all plain folks. Even Henry James was revealed as a man of very simple make-up when stern necessity drove him to it, and what necessity is sterner than making a business go? The average man or woman has mighty few words in stock, compared with the coldstorage heap in the dictionary. They are the words that are used every day. You use them, I use them, we hear them all day long. Base your ad talk on your spoken talk and you will not go far astray. Give people credit for being impressed with something besides shrieks and wild verbal war-dances.

"Begin your ad with the beginning of the subject. Don't imitate the lightning bug, which is said to be 'a beautiful bird, but hasn't any mind. He dashes through this world of ours, his headlight on behind.'

“Get your headlight on in front, so that folks can tell at once which way you are going. If it is 'fountain pens' you are talking about, say 'fountain pens' in the headline. Treat your headings exactly as the newseditor treats his. He tells the whole story in snappy brief. He assumes that people will read what follows either because the heading draws them or because they are interested in the subject." The Right and Wrong of Figuring Percentage.

Probably the majority of merchants make use of percentage in figuring profits and marking prices, but beyond that its application in its simpler form is largely for statistical purposes.

It seems to be true, remarks a writer in the American Penman, that the average person is unable to cope with the ordinary problem in percentage if it goes beyond one operation.

Failure to couple the rate with its base leads to many very common errors. The problem which follows will illustrate my meaning:

“An article costing $50 was marked to sell at 40 per cent above cost. If a discount of 40 per cent was

Dunning Letters.

"Form" dunning letters are inefficient, according to the Publishers' Guide. They lack point. They do not convince. A form letter is easily recognized. The man who receives a mimeographed dun immediately comes to the conclusion that he is not singled out personally, but is included in a mass. If the firm has so many outstanding debts, and is so rich that it can afford the luxury of resorting to "form" letters, he is not likely to worry.

Every debt is worth a personal effort. A letter written to each man, to suit his particular case, is convincing, and usually brings results. In case the total amount is not settled, a portion is paid; while the number who ignore or make excuses is few compared with the total who respond.

A personal letter to each debtor is economy, for it brings returns, and whatever brings the greatest return, economically, is efficient.

Required of the Man in Charge.

A manager must learn, says the Confectioners' Gazette:

To talk directly to the point.
To decide quickly in emergencies.
To infuse loyalty among employees.
To waste no time in non-essentials.
To insist on quality in service rendered.
To find and stop leaks that sap profits.
To hold heads of departments to strict account.

To plan ahead, and anticipate both needs and dangers.

To get rid of inconsequential callers quickly yet courteously.

To understand details, but leave their execution to subordinates.

To promptly detect and remedy any jar or friction in the business machinery.

“As aspirin is not completely soluble in water (1 part dissolves in 125 parts of water) I added 1.5 grammes of sodium bicarbonate in order to produce a clear solution. Was I correct in doing so or did I destroy the therapeutic value of the mixture?

2. "I would also like a formula for making a 'fuid tolu, soluble' to be used in preparing syrup of tolu.

3. “Can you tell me the name of a good work on industrial chemistry and also where it may be obtained?"

1. When aspirin is mixed with bicarbonate of soda it is probable that a salt of aspirin is formed which shortly is converted into sodium acetate and sodium salicylate. As the therapeutic efficiency of the aspirin is thus destroyed it is inadvisable to effect solution by the means you adopted. The aspirin should be dispensed separately or the prescription put out as a shake mixture.

2. A "soluble tolu" for use in making syrup of tolu may be prepared as follows: Mix 200 Cc. of alcohol with 400 Cc. of glycerin, and dissolve 100 grammes of balsam of tolu in the mixture with the aid of heat, avoiding loss by evaporation. Next add 400 Cc. of water, and allow the mixture to become cold. Pour off the milky liquid from the resinous precipitate (which latter is to be rejected), mix it with 10 grammes of magnesium carbonate, by trituration, and filter. Lastly, pass enough of a mixture of one volume of alcohol and two volumes of water through the filter, to make the whole filtrate measure 1000 Cc. A mixture of 32 Cc. of this preparation with 468 Cc. of syrup yields a product which may be used as syrup of tolu in all cases where the official preparation is not required.

3. “Industrial Chemistry,” edited by Professor Allen Rogers of Pratt Institute, New York City, is the title of a book which is said to contain much valuable information on the subject. The American edition is published by the D. Van Nostrand Co., 25 Park Place, New York City, at the price of $5.00 net; the English edition is obtainable from Constable & Co., Ltd., London, England, at the net price of 24 shillings.
