These three animal fertilizers were of a good mechanical 

 condition ; and the analytical results correspond very satis- 

 factorily with the represented composition of their respec- 

 tive manufacturers. The presence of a considerable amount 

 of potassiiun oxide in No. III. cannot fail to increase the 

 chances of success wherever potassa is but in limited quan- 

 tities in the soil, — a circumstance not unfrequently met 

 with.
