steeped in toiling water, hay being at the same time supplied; 
and in the malt experiment the amount of grain having been 
pushed further than in the case of barley, it was considered ad- 
visable to give a similar trial to that of grain. The result of this 
went to prove, that no advantage is gained by giving so much 
grain; but, that, on the contrary, a deteriorating effect is pro- 
duced. The comparison may be thus stated : — 
I. Milk; 
lbs. of milk. 
100 lbs. of mixed barley, hay, and grass, produced 8*17 
100 lbs. of mixed malt and hay produced 7.95 
II. Butter; 
lbs. of batter. 
100 lbs. of barley, hay, and grass, produced 1*95 
100 lbs. of malt, and hay produced 1*92

According to this view of the experiment, it appears that the 
malt produces a smaller amount of milk and butter when com- 
bined with hay, than in the barley experiment; and that the cat- 
tle were losing weight, and consequently strength, daily. In 
whatever manner, therefore, we view the experiment, this is an 
insurmountable objection to the use of malt — that it is not capable, 
when used in any quantity, comparatively with barley, to sustain 
the weight and consequent strength of animals. But there is an- 
other aspect in which the experiment should be examined, and 
this is obviously the correct one, since a larger quantity of malt 
was used than of barley. If we consider the hay a constant quan- 
tity, and then calculate the amount of product which would com- 
paratively result from such grain, the consequences would be as 
follows : — 
I. Milk; 
100 lbs. of barley would produce 34'6 lbs. dry milk. 
100 lbs. of malt would produce 26"2 do. 
II. Butter; 
100 lbs. of barley would produce 7'66 lbs. of butter. 
100 lbs. of malt would produce 6"35 do. do. 
By the present mode of comparison, then, it appears that, in 
every point of view, malt is inferior to barley as an article of diet 
for cattle, as it gives less milk and butter, and diminishes the live 
weight, instead of increasing it, which barley does under the same 
circumstances. — p, 104 — 105.
