With the following table the printer dispenses entirely with a type measure proper, resorting to the common inch rule. getting the square inches in his job, he may take the figures directly from the table, or, if the square inches are in excess of the table, add two or more of the numbers together; as, for instance, 79 square inches of brevier, the seventh line gives 567 ems for 7 inches, add a cipher and you have 5.670 ems for 70

inches, and in the ninth line add 729 ems to the 5,670 ems, and you have a total of 6,399 ems in 79 square inches.

TO FIND WEIGHT OF A GIVEN SIZE TO CORRESPOND WITH BULK OF SAMPLE. RULE-To find weight required for a given size to correspond in thickness with a given sample, multiply the weight of sample by the dimensions of sheet required, and divide by the product of the dimensions of sample. The table below gives all the regular sizes:

For 32x44 (which is just

double 22x32) multiply the figures of 22x32 by 2. Like

wise 38x50 is double 25x38, etc. For odd sizes proceed as per rule above..

40 x 48.

Almanac predictions can be nothing but conjecture, the earth's subjection to many unknowable and undeterminable forces rendering such calculations impossible. It is practicable, however, by the following rules, drawn from actual results during very many years and applied with due regard to the subjects of solar and lunar attraction with reference to this planet, to foresee the kind of weather most likely to follow the moon's change of phase.

OBSERVATIONS.-I. The nearer the moon's change, first quarter, full and last uarter to midnight, the fairer will be the weather during the next seven days.

2. The space for this calculation occupies from ten at night till two next morning. 3. The nearer to midday or noon the phase of the moon happens, the more foul or wet weather may be expected during the next seven days.

4.

The space for this calculation occupies from ten in the forenoon to two in the afternoon. These observations refer principally to summer, though they affect spring and autumn in the same ratio.

5. The moon's change, first quarter, full and last quarter happening during six of the afternoon hours, i. e., from four to ten, may be followed by fair weather, but this is mostly dependent on the wind as is noted in the table.

6. Though the weather, from a variety of irregular causes, is more uncertain in the latter part of autumn, the whole of winter and the beginning of spring, yet, in the main, the above observations will apply to these periods also.

7. To prognosticate correctly, especially in those cases where the wind is concerned, the observer should be within sight of a vane where the four cardinal points of the compass are correctly placed.

MEN must learn that in this theater of man's life it is reserved only for God and the angels to be lookers-on.-LORD BACON.

"OLD men for council, young men for war," is the motto on which a Senate is constituted. When Rome was sacked by the Gauls the Senate thought it unbecoming in their body to withdraw with the rest of the population. The barbarians So they sat at their several thresholds and calmly awaited the end were amazed at the white-bearded figures and regarded them at first with some awe. Gradually they dared to stroke their beards and pass their hands over their bodies. At length finding that they were but mortal men they destroyed them. The Constitution of the United States recognizes the importance of age in limiting eligibility to the Senate to those who have reached the age of thirty years.

Certain phenomena in the air and peculiarities of birds have long been known to indicate a change in the weather. Many years ago the learned Dr. Jenner embodied these in verse, in reply to an invitation from a friend with whom he had planned an excursion the following day. It embodies about all that is known to-day upon that branch of the subject, and we reproduce it as being reasonably correct:

The hollow winds begin to blow,

The clouds look black, the glass is low;
The soot falls down, the spaniels sleep,
And spiders from their cobwebs peep.
Last night the sun went pale to bed,
The moon in halos hid her head;
The boding shepherd heaves a sigh,
For, see, a rainbow spans the sky;
The walls are damp, the ditches smell,
Closed is the pink-eyed pimpernel.
Hark! how the chairs and tables crack,
Old Betty's joints are on the rack;
Loud quack the ducks, the peacocks cry,
The distant hills are looking nigh.
How restless are the snorting swine,
The busy flies disturb the kine;
Low o'er the grass the swallow wings;
The cricket, too, how sharp he sings;
Puss, on the hearth, with velvet paws,
Sits, wiping o'er her whiskered jaws.
Through the clear stream the fishes rise,
And nimbly catch th' incautious flies;
The glow-worms, numerous and bright,
Illum'd the dewy dell last night.
At dusk the squalid toad was seen,
Hopping and crawling o'er the green;
The whirling wind the dust obeys,
And in the rapid eddy plays;

The frog has changed his yellow vest,
And in a russet coat is dressed.
Though June, the air is cold and still;
The blackbird's mellow voice is shrill.
My dog, so alter'd is his taste,

Quits mutton bones, on grass to feast;
And see yon rooks, how odd their flight,
They imitate the gliding kite,

And seem precipitate to fall

As if they felt the piercing ball.

"Twill surely rain. I see with sorrow,

Our jaunt must be put off tomorrow.

THE most dreadful earthquake on record is that which, November 1, 1775, destroyed the city of Lisbon, Portugal. The only warning the inhabitants received was a noise like subterranean thunder, which, without any considerable interval, was followed by a succession of shocks which laid in ruins almost every building in the city, with a most incredible slaughter of the inhabitants (60,000). The bed of the river Tagus was in many places raised to the surface, and vessels on the river suddenly found themselves aground. The waters of the river and the sea at first retreated, and then immediately rolled violently in upon the land, forming a wave over forty feet in elevation. To complete the destruction a large quay, upon which great numbers of the people had assembled for security, suddenly sank to such an unfathomable depth that not one body ever afterwards appeared at the surface.
