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 ihe 

 disagreeable effhivia 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. 



SOFTNESS OF 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 and elastic the 

 filament, the softer the wool ; and the degree of ductility and elasticity can be measured 

 with the utmost minuteness and certainty with the above named instrument. 



OF BREEDING AND RAISING SwiNE FOR THE BRISTLES. The following is a 



Statement of the quantity and value of Bristles imported annually into the United States, 

 from the \st October, 1842, to the 30th June, 1849.

This furnishes an average of 380,264 Ibs. 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 1o furnish them of qualities adequate to her wants, there 

 would be no ground of complaint; but, by a reference to the statistical table accompany-
