t ic hi to "a little com meal.'' The average loss in weight of one lot 
was 0.9 pound per week, and of the other lot 1.6 pound-. This loss 
was not due to lack of capacity, since in a similar experiment with 
mangolds, which contained as great a percentage of water as the eom- 
frey, the hogs ate twice a> much. 
Another test with older pigs was made, using for the first six weeks 
a ration com pose, I entirely of grain : the next four weeks a rat ion t hat 
was ."ai per cent coin ensilage; and the remaining five weeks of the 
period a ration containing 50 per cent of comfrey. The comfrey was 
\'n\ I'reshK cut and contained an average of 86.7 per cent of water. 
In considering the cost per pound of gain, the green comfrey was 
rated at 81 a ton. In one pen the comfrey and ensilage were salted, 
while in another pen the green feed was not salted. Neither lot of 
j)ii^s made a profitable growth while comfrey was fed, and the cost 
per pound of gain in live weight for the period they were U'A comfrey 
was 9.53 cents in the pen where sail was not applied and 6.12 cents 
in the pen where salt was applied, as against 3.38 cents in the first 
pen and 3.07 cents in the second pen when ivd the grain ration. 
VALUE OF PRICKLY COMFREY AS HAY OR ENSILAGE. 
Regarding the use of prickly comfrey, the New York Agricultural 
Experiment Station reports" as follows: "Our trials indicate that it 
is of no value either for hay or ensilage. Its use, therefore, is con- 
fined to that of a soiling crop." In Europe it has been used to sonic 
extent for silage, hut the watery and gummy nature of the leaves is 
apt to cause it to heat in the silo and acquire a disagreeable odor. 
CROP YIELDS.
