To Cure Sea-sickness PAUL KAPPMEIER of Altkloster, 1 Germany, has recently invented a device, called "Neptune's Cap,” which is said to provide a certain mechanical cure for sea-sickness. The device, which is the result of much study and investigation, depends for its efficacy on the fact that the principal cause of sea-sickness is cerebral anaemia, the blood of persons so affected running from the head to the gastric regions. By means of heat, furnished by small electric radi

an invention which he says will permit
each property owner to settle the question
himself. He can have the street in front
of his property as wet or as dry as he
pleases. And in addition
the expense to the city of
providing the old fash-
ioned water-cart will be
eliminated. His solution
of the difficulty takes the
form of a curb attach-
ment which will sprinkle
one side of the street
whenever the water is
turned on by the indi-
vidual householder. A
metal tube, perforated
on the outer side, is im-
bedded in the concrete
curb. This tube is con-
nected with a street hy-
drant, and when the wa-
ter is turned on tiny
streams gush from the
holes in the tubing and
sprinkle the street as long as is necessary.
Figure number one shows a section of
the curb with sprinkling attachment in
place, and figure two shows how the de-
vice looks from the street.

Shocking She was a pretty little woman from the interior of the State, and she boarded Conductor Mulligan's car to come to St. Johns to visit her sister-in-law. She had but little knowledge of the trolley system, and viewed everything along the route with intense interest. "If I should put my foot on that rail,” said she, pointing to the nearest bit of track, "would I get a shock?” Mulligan smiled. “Not unless you put your other foot on the over-head wire!" replied the suave conductor. The dear woman almost fainted.–St. Johns (Ore.) Review.

ICHALK

TALKS I

by CARL S. DOW.

Vignetting T is an almost invariable rule : that, sooner or later, the

photographer wishes to make prints of various shapes and sizes, or pictures with the less important objects so printed that they are subordinate to the rest. Or, if he be engaged in portraiture, or in the preparation of prints for half-tone plates. he will make vignetted pictures, which have a promi

nent central figure and the edges gradually fading to white. Common examples are seen in studio portraits.

Vignettes To make a vignette, the negative is

ette. the negative is commonly made as for a “square finish,”

itself is partially, sometimes wholly, prepared for vignetting ; that is, the interposition of a suitable serrated screen during exposure so obscures the light from the lower portion of the figure that the head and shoulders only are prominent. This scheme is advantageous, when the background is to be dark to the extreme edges of the print, but has the disadvantage of making it imperative to always make a vignette from that negative, while the ordinary negative can have either style of print taken from it.

There are three methods of making the vignette, all of which have for their object the shutting off of the light from the edges. To make the change from deep tones to white, gradual, requires constant movement, or the placing of the edge which shuts off the light far enough from the negative to prevent a sharply defined line. A little experimenting will show how the vignette can be made. Cut a circular hole in the cover of a negative box and place it on the face of a printing frame, about one inch from the glass, the vertical sides of the box shutting out the light. Now if the frame is exposed to a north light or placed in the shade, the result will be a fairly satisfactory vignette. If the printing must be accomplished in less time, cover the hole with tissue paper and print in the full sunlight. Another way is to cut the hole of the desired shape in a sheet of cardboard and print in the sun, keeping the cardboard moving slowly to prevent a sharp line. For these ways of vignetting, the hole is often made serrated, the teeth and the spaces making a more gradual change of depth of color. The third method is a device which can be purchased from dealers for a small sum. The “home made” outfit answers all purposes, however.

To hold back the shadows, a piece of paper cut to the shape of the thin part and moved slightly on the negative while printing, should be used during part of the process.

Letters To get the narrow white line around pictures printed as letters or in various shapes, as shown by the initial letters of this and the preceding Chalk Talk, the desired shape is cut out of thin black paper such as comes around dry plates. This paper is used as a mask in the printing; it is placed between the film of the negative and the paper, so the resulting print will have a wider border of white, which may be trimmed to the desired width after toning or developing.

The two illustrations on the accompanying plate are suggestions for this work, the combination of masking and vignetting being particularly effective for certain classes of picture.
