the new-comers in the light of intruders, which she too frequently 
punishes with death. To obviate this he puts the first hen that 
hatches into a coop, and keeps her there with her chickens till 
another hen hatches, when he substitutes the second hen for the 
first, leaving the charge of the former; and when another hen 
hatches, she is put in place of the second, with all three broods — 
if the aggregate number do not exceed thirty, which he says she 
will take care of affectionately and efficiently. 
Feecundity of Hens. — A young hen will lay the first year about 
150 eggs; the second 120; the third 100; diminishing every year 
as she grows older; and says the editor of the Maine Farmer, she 
should " go to pot " after the fourth. 
Analysis of the Egg. — M. Gobley has submitted to the Paris 
Academy of Science, an account of his analysis of the egg. In a 
former paper he stated that the yolk contains oleic, margaric and 
phosphoric acids; he now informs us that he has also found water 
and an albuminous substance, salts, lactic acid, two coloring sub- 
stances, &c. 
A Curious JVesf. — A cute Yankee has invented a hen's nest, 
in the bottom of which there is a kind of trap-door, through 
which the egg, when laid, immediately drops; and the hen, look- 
ing round and perceiving none, lays another. — Boston Paper. 
SUBSOIL PLOWING. 
BY N. GOODSELL. 
Much has been published within a few years past, on the sub- 
ject of subsoil plowing, and various patterns of plows have been 
manufactured and recommended to the public, for loosening the 
soil to a greater depth than is usually done with the common 
plow ; some of which I think h^ve been of great service to our 
farmers; but I have seen some subsoil plowing the past season, 
which for economy in doing the work, and beneficial effects when 
done, I think preferable to any I have ever examined. This work 
was done with a plow manufactured in Massachusetts, by Messrs. 
Ruggles, Nourse & Mason, sold in Rochester as the " Eagle Sward 
Plow." The land in which this plow was used was smooth, free 
from stone, and had been mown many years. The plow was in- 
troduced in " full dress," having its gage-wheel and coulter at- 
tached, and gaged to cut from six to eight inches deep, and was 
drawn by three good horses. The first furrow was cut and laid 
flat — the second round, the gage-wheel was made to run in the
