424 ANIMALS AND THEIR PRODUCTS. 



pork, mutton, tallow and lard, unless its price should 

 happen to be very low, not more than three-fourths 

 that of corn, which seldom or never happens, it can 

 not be used advantageously. 



220. Experiments have shown that on deep loams, 

 carrots may be raised to great advantage. Though not 

 less than 85 per cent, of their weight is water, yet the 

 quantity that can be grown on an acre is such, as to 

 leave a very large amount of solid food, after deduct- 

 ing 85 per cent. They are excellent for horses, if given 

 in small quantities, and with discretion, so as to pro- 

 duce on the bowels a slightly relaxing effect. When 

 given as food in part to milch cows, the tendency is to 

 keep the animals in a healthy state, and to impart a 

 yellowness and richness to their milk, with none of

 nips. They are excellent also for any kind of stock 

 cattle, when fed upon too large a proportion of coarse 

 and not very juicy hay. Carrots, as well as turnips, 

 potatoes, and other roots, should, if possible, be kept in 

 cellars that are cool. The nearer they can be kept to 

 the freezing point, and yet not freeze, the better ; for 

 if too warm they sprout and become dry and pithy, 

 which greatly diminishes their value. 



221. Turnips contain from 85 to 90 per cent, of 

 water; 7 or 8 of pectine (a substance similar to 

 Btarch) ; about 2 of gum and sugar ; from 1 to 2 of 

 nitrogenous matter; less than 1 of oil; about 2 of 

 woody fibre ; and 1 of ash. The turnip is less nutri- 

 tious than the carrot. It cannot so advantageously as
