cent, dry matter, and generally less than two per cent, of protein. 

 Leaves are somewhat more digestible than twigs, and the better 

 kinds compare favorably, in feeding value, to meadow hay. 

 Leaves of the ash, birch, linden and elder are considered of 

 greatest value, in the order given. They are eaten with relish, 

 especially by goats and sheep, and are often harvested in the fall 

 and dried for winter feeding. 



III. Slaughter-house and Beet-sugar Factory Refuse. 

 Digestible nutrients and fertilizing constituents. 



338. Dried blood. Dried blood from the slaughter-house is 

 used for the most part by farmers and gardeners for fertilizing 

 purposes. Such use seems a perversion, for it should first be 

 employed as a feeding stuff and the voidings of the animals to 

 which it has been fed applied to field and garden, thus securing 

 two values. Dried blood may serve a useful purpose with the 

 stockman, especially the pig feeder. We have learned that corn 

 lacks protein; dried blood is a complementary food, since it is 

 remarkably rich in protein. Pigs at weaning time will relish a 

 tablespoonful of dried blood daily with their feed, and this allow- 

 ance may be gradually increased until two ounces are fed daily to 

 each animal. Those feeding pigs, especially if handling breeding 

 stock, should not allow the gardeners to have first claim to such a 

 useful adjunct to the short list of really desirable feeding ma- 

 terials usually available. See Chapter VI. (778, 902) 



339. Flesh meal, meat scrap. The introduction of meat scrap 

 or flesh meal as a feed for stock is due to the efforts of Baron 

 Liebig, at whose instance the first factory for making meat extract
