3. Notes ox Sludge, its Agricultural Value. 

 The interest in the character of this class of materials and 

 their value for manurial purposes is deservedly steadily in- 

 creasing, judging from inquiries received at this office. As 

 the source of the article as w^ell as the mode of collecting the 

 same may differ widely, it is but natural that no definite 

 advice can be furnished without a special examination into 

 the existing circumstances. The suljsequent compilation of 

 analyses of sludge, made at the request of farmers of the 

 State, are published to increase a more general interest in 

 the matter : —
