of the lower animals, we entertain no doubt but that the rule extends to them. We 
recollect having heard the late much-respected Samuel Coats (who was one of the founders, 
and for many years one of the managers, of the Pennsylvania Hospital,) say, that at one 
time they kept a few hogs in the yard of that Institution, and that, in order to avoid the 
disagreeable effluvia generally arising from such animals and their pens, he had them both 
well scrubbed every morning, and that the hogs’ hair became fine, soft and lustrous. 
And we, with confidence, refer the intelligent reader to the history of Cattle and Sheep 
raising and breeding in every country where they have attained any celebrity, for the fact 
that success depends much upon the knowledge, the care, and the perseverance of the 
farmer. Bakewell, in 1789, was in the receipt of 3,000 guineas a year for the hire of 
rams, and seven of them sold for 2,000 guineas! But this was the result of unremitted 
‘ care and attention to his flock for a long series of years. He commenced his experiments 
upon the old Leicester breed, and he continued them, without any crossing whatever. end- 
ing with the new Leicesters, of the value above mentioned. He paid too little attention 
to the wool, as we will hereafter notice; but, in other respects, his experiments were 
crowned with complete success. 
Sorrness or StapLe.—There is a delicate, silky, highly elastic feeling in wool that is 
very desirable. This softness of texture is usually judged by passing it through the 
fingers or over the inside of the lips, but may be determined with the trichometer, it agree- 
ing with the ductility and elasticity of the filament. The more ductile an1 elastic the 
filament, the sofier the wool; and the degree of ductility and elasticity can be measured 
with the utmost minuteness and certainty with the above named instrument.

This furnishes an average of 380,264 lbs. per annum, worth $174,311. 
Now, if the United States were incapable of producing bristles enough for her own 
consumption, or if she was unable to furnish them of qualities adequate to her wants, there 
would be no ground of complaint; but, by a reference to the statistical table accompany-
