1. Analyses of Materials sent on for Examination. 



During the past season 225 materials have been received, 

 and the results of our examination have been published in 

 detail in bulletins 59, 62 and 63 of the Hatch Experiment 

 Station of the Massachusetts Agricultural College, together 

 with the results of the official inspection of commercial fer- 

 tilizers. 



The responsibility of the genuineness of the articles sent 

 on for examination rests in all cases with the parties asking 

 for analyses, and our publication of results merely refers to 

 the locality they come from. It is evident, from the increase 

 each year of the number of materials sent in for analysis, that 

 there is a growing interest taken in this work, and individuals 

 are realizing the value of such chemical investigations. 



The waste products of many industries are of such a nature 

 that their value as manurial substances is unlimited and the 

 current modes of manufacture are constantly undergoing 

 changes which affect seriously their commercial manurial 

 value. A frequent investigation of this class of materials 

 cannot help but prove beneficial to the farmer, and hence 

 arrangements will be made, as in previous years, to attend 

 to the examination of these materials to the full extent of our 

 resources. This work is carried on free of charge to the 

 farmers of this State, the results of analysis being returned 

 in the order of the arrival of samples at the office. Below
