 the influence exerted by the chlorids and tin- magnesia present are reported, ft is 

 reported that in all tin- experiments tin- kainit acted favorably and there was noth- 

 ing to indicate that the chlorin or magnesia content interfered with the growth of 

 the plant-. The authoi therefore is inclined to believe that cases of depression of 

 yield by kainit musl be restricted to soils which contain an excess of chlorids or mag- 

 nesia, a condition which can he corrected by applications of lime.

 I'll. Ill 88). — This is a report of a committee appointed by the- Board of Agriculture 

 and Fisheries \>> inquire into the efficiency of this act as a means of preventing fraud. 

 The general conclusion reached is that while the act has in general been of great 

 benefit t" the [arming class in suppressing many forms of fraud and in causing manu- 

 facturer.- to exercise more scrupulous can- in the preparation of their product-, it has 

 not been of asgreal benefit as it was hoped it would be to small farmers who are most 

 in need of it- protection. This is attributed mainly to apathy and lack of informa- 

 tion on the part of the small farmers, and the remedy proposed is education in its 

 wiliest sense. Detailed recommendations, which it is believed will render the 

 enforcement of the law more efficient and beneficial, are made. Among these 

 recommendations are greater care in sampling to secure representative and authentic 

 samples, the requiring of a guaranty of composition, more uniform methods of 

 analysis and of procedure in prosecution of violations of the law.
