prepared by the draftsmen. Tlie office 
hours are from 8.45 to 11.45 in tiie morn- 
ing, and from 1.15 to 4.45 in the afternoon. 
So satisfied has the firm been with the 
result of the experiment that they are 
now making arrangements for the intro- 
duction of more ladies into their various 
departments." Young ladies are pecu- 
liarly adapted for this class of skilled 
labor, and we have seen excellent original 
work turned out by a young lady who 
had devoted several months to the prac- 
tice and study of drafting. 
The Heavens. 
BY BERLIN H. WEIGHT. 
THE PLANETS.— APRIL, 1883. 
Venus and Mars are becoming: closer com- 
panions in their lonely march through desolate 
regions, where but few stars are visible to the 
naked eye, and tlie objects visible with moder- 
ate telescopes are quite as rarely met with. 
Venus, at the beginniu^^• of the month, is di- 
rectly below the A in Aquarius -see the figure 
at the upper right-hand corner of the illustra- 
from which it will be seen that the A in the 
northwest corner of the constellation is the only 
figure by which it may be readily identi- 
fied. The region upon the east of the Equinoc- 
tial Colure or for a much greater distance east- 
ward is still more barren of prominent stars 
or figures. It would be very convenient some- 
times if a fine star existed at the point where 
the earth's path intersects the Equinoctial Co- 
lure or First Meridian of the Heavens (cor- 
responding to the meridians of Washington or 
Greenwich upon tlie earth), and the equator of 
the lieavens. But the best way of locating this 
point is by aid of tlie A and the two second mag- 
nitude stars which form the E. side of the Great 
Square of Pegasus, which lie almost exactly on 
the Equinoctial Colure, at about the width of 
the Ecliptic (16°) above the point of intersec- 
tion. 
The bright star Fomalhaut lies directly in a 
line with Venus and the A, at about three times 
their distance apai-t below. 
Venus rises on the 10th at4h. 3m. morn.; 20th, 
3.51 morn., and 30th, 3.40 morn. Mars rises on 
the 10th at 4h. 34m. morn.; 20th, 4.13 morn., and 
30th, 3.52 morn. 
The Moon passes Venus on the 4th, being 
nearly 6° north, and she reaches Mars the next 
day, passing about the same distance north of 
him (see cut). Venus passes within less than 
Fig. 1. 
tion, Fig. 1, which also shows the relative posi- 
tions of Mars, Venus, the Moon, and principal 
stars of this region. 
All of the stars down to tlie fifth magnitude, 
which are in that portion of the ecliptic allotted 
to the constellation Aquarius, are here charted, 
one-half of a degree of the fourth magnitude 
star Lambda Aquarii on the morning of the 
10th, being south of the star. 
Jupiter sets on the 10th at 11.55 eve.; 20th, 
11.23 eve.; 30th, 10.52 eve. He will be 4° north 
of the Moon on the 11th.
