From all which we deem ourselves warranted in inferring, that the strength of pile 
depends, in a great measure, upon the vital power of the animal upon whom it grows, from 
which we deduce the following corollary, viz: that the breeder of Sheep, who would 
require strong fleece, must, by attention to their food, cleanliness, and preservation from 
inclemencies of weather, endeavor to preserve, and, tf possible, increase their VITAL POWER. 
A feeble Sheep cannot produce a strong wool; it is contrary to principle as well as our 
experiments, and must not be anticipated. 
Combe, on the duration of human life, from tables of mortality in Edinburg, shows that 
what he calls ¢he gentry (by which he means the class between the nobility and the arti- 
sans) have a mesne average age of 433 years; while artisans, laborers and servants, have 
an average age of only 273 years; and we think that the reason of this disparity is to be 
traced, mainly, to premature loss of vital power by the reckless among the second class— 
which loss would doubtless, by careful experiments, be discovered in their hair. ‘The 
American Sheep breeder should have none but gentry in his flock. 
OF THE FINENESS or FLEeEce.—We entertain the opinion, that even the fineness of 
fleece may be increased by continued care and attention; good, wholesome food, in sufh 
cient quantity—preservation from the inclemencies, and particularly from the sudden 
changes, of the weather—and cleanliness; these are the means by which the integuments 
may be improved in fineness, as well as in other useful qualities ; while starvation and 
exposure to cold, sudden changes, dampness and filth will, in time, show its effects in a 
contrary direction. 
In turning over the leaves of our book, which contains “locks of the hair of the heads 
of distinguished individuals,’ every one is struck with the fineness, the softness, and 
the lustre of a large majority of the specimens, when contrasted with our collection of 
hair of the inmates of the alms-houses and hospitals, i. e., of the unintelligent and reckless, 
who have been in the habit of living uncomfortably. From our examination of the pil’
