easily kept, and great layers, in consequence of which they have 
obtained the name of “ everlasting layers.” 
The Poland fowls resemble tlm .Spanish in everything except 
appearance. They are jet black; vdth a characteristic white top- 
knot, and are by many considered tile handsomest variety known. 
Having had sotne experience with each breed/1 can unhesitatingly 
recommend them, as they are well adapted to J/he wants of the farmers 
of the Middle States. 
I should have mentioned, however, that none of the breeds noticed 
above are gdod sitters ; therefore, a few hens of other breeds should 
be kept for the purpose of hatching the eggs of these, and rearing the 
young. 
INSECTS. 
INSECTS FREQUENTING THE COTTON-PLANT. 
BY TOWNEND GLOVER. 
The cotton-plant, furnishes food for numerous insects, 6ome of which 
feed exclusively upon the leaf, some upon the flower, while others 
destroy the young buds and bolls. It is my purpose to describe these 
insects, not in the order of their classification by natural families, but. 
according to the part of the plant they most generally frequent, or 
to which their ravages are chiefly confined. Thus, by referring to 
the parts injured, one can easily recognise the insects, or their lai vm, 
which attack them in any of the stages of their existence. 
Many of these insects at first appear in small numbers, and only 
become formidable in the second or third generation , for instance, if 
a female boll-worm produce 500 moths, one-half of which are males 
and the other half females, the next generation, if the increase be in 
the same ratio, will amount to 125,000 cattcrpillars or moths , and 
all this is accomplished in the space of a few weeks. It will there- 
fore be perceived that their destruction depends upon prompt and 
timely action ; and planters may materially aid in carrying out a 
work designed for their mutual benefit, by minutely observing the 
habits and characteristics of these pests of our fields, devising means 
for their destruction, and communicating the results of their ob- 
servations and experiments, through some appropriate channels, to 
the public. . 
Insects injurious to the cotton-plant consist of those very destruc- 
tive to the general crops, such as the boll-worm, cotton caterpillar, 
and some others ; and those which do comparatively little injury, 
their numbers thus far not being sufficiently great to cause much 
damage, such as the leaf-rolling caterpillar (tortrix) and several
