DENTITION AND DIET. 138 
the same, It is the young and growing animal that requires our 
greatest attention. If our readers desire to raise colts that shall 
remunerate them for the trouble and expense incurred, the: must 
feed the same, during their minority, with a liberal] hand. Any 
neglect at this period can never be made up in after life. The 
subject will always remain lank and lean—living monuments of 
their master’s folly or ignorance, as the case may be. In addition 
to the food required for the colt’s growth, we must also furnish 
enougl, to supply the waste incurred by expenditure of muscular 
power. Weall know that the young are very active and playful. 
Every muscular movement involves an expenditure of vital force, 
and thus exhausts the system; therefore, in view of developing 
their full proportions, and promoting the integrity of the living 
mechanism, they must have nutritious food, and plenty of it. They 
are not, however, to have a large quantity at a time, but little and 
often. Their stomach is small, not larger than that ut a man’s. 
Should it be overdistended with innutritious food, the organs of 
respiration and circulation become embarrassed, and tne blood 
loaded with carbon. They require food often, because tne diges- 
tive organs are very active, and soon dispose of an ordinary meal. 
Then comes the sensation of hunger, which every one knows is 
hard to bear. 
The climate or temperature of the surrounding atmosphere has a 
wonderful effect on the animal machine. Let two horses be located 
in different stables, one of which shall be, like “Jack Straw’s’ 
house, neither wind-tight nor water-proof; the other built on 
tne air-tight principle. The occupant of the former will require 
more fvod than he of the latter, because cold air has a depressing 
influence on the body, exhausting superficial heat. Gur readers 
are probably aware that if a hot brick be placed in contact with 
a cold one, the caloric radiated from the first is absorbed by the 
latter, until a sort of equilibrium be established. The same is 
true as regards the body of a horse. He being in an atmosphere 
many degrees less than that of his own body, gives off the heat 
af the same to the surrounding medium. The heat thus given 
off has to be replaced by food, which is the combustible material. 
But it often happens that the digestive organs are deranged, in- 
capable of assimilating a sufficiency of carbonaceous material to 
maintair. even the normal temperature of the body. The conse-
