BULLETIN 69, U. S. DEPARTMENT OF AGEICULTUKE. 



The more extended feeding of the summer was done in the case of 

 sheep. Table IV shows a summary of these experiments. In addi- 

 tion to the thh'teen animals listed in the summary, two (Nos. 145 

 and 152) were brought in for feeding, but ate so Httle that they are not 

 included in the sum total of the summer's work. Five of the sheep 

 (Nos. 136, 137, 149, 151, and 158) were fed upon the leaves and stems 

 of Cicuta and received, per 100 pounds of weight, from 11.4 pounds, 

 in the case of No. 137, to 143.3 pounds, in the case of No. 158. These 

 amounts were fed in periods varying from one week to about ten days. 

 None of the animals suffered any iU effects from the feeding, although 

 in the case of No. 158 it ate of the plant nearly 50 per cent more than 

 its weight. In aU of these cases the sheep were fed exclusively upon 

 the leaves and stems, with the exception of one or two cases, like 

 No. 136, where a little hay was mixed with the material in order to in- 

 duce the animal to eat it more readily. Nos. 157 and 143 were given 

 leaves, stems, and flowers, mixed with enough hay to induce them to 

 eat it more readily. No. 143 in eleven days ate 16.5 pounds per 100 

 pounds of weight, while No. 157 in ten days ate 109.1 pounds, or 

 just about the equivalent of its weight. . Neither of these animals 

 suffered any ill effects.
