EXPERIMENTAL FARMS

was substituted for lime. The lime emulsions were first proposed and made by Pro- 

 fessor Close, of the Delaware Experiment Station, and we found them fairly stable, 

 homogeneous, easy to spray and not clogging the nozzle. The flour emulsions, sug- 

 gested by the writer, were also shown to answer equally well, if required for immediate 

 use. 



(c) The action of solutions of Formalin on the vitality of wheat has been ascer- 

 tained and the strength of certain brands of Formalin has also been determined. The 

 large quantity of this chemical now used in the North-west in the treatment of grain 

 for the prevention of smut makes the information now given timely and valuable. 



(d) The relative efficiency of certain cyanides, used in the production of hydro- 

 cyanic acid for the fumigation of trees and shrubs for the destruction of the San Jose 

 scale is given. 



Fodders and Feeding Stuffs. — In addition to the tabulation and discussion of a 

 number of analyses of concentrated feeding stuffs and condimental foods made during 

 the past year, we present the results of the examination of the chief field roots, and show 

 that marked differences in feeding value may occur. The influence of heredity or 

 ' breed ' is also shown by examples of two well known varieties of mangels. 



Sugar Beets. — Three varieties usually grown, for factory purposes, Vihnorin's Im- 

 proved, Klein Wanzleben, and Tres Riche, as grown on the Dominion Experimental 

 Farms during the past season have been analysed as to their sugar content. 



Well Waters. — One hundred and sixteen samples of water from farm homesteads 

 have been received. The tabulated results from 83 of these are given, together with a 

 short report on their quality from the sanitary standpoint. 



Samples Received from Farmers. — The number of these continues to increase. A 

 large proportion of them have been examined and reported upon. This very useful 

 branch of our work, though affording very little material for the annual report, is one, 

 I believe, of imme.nse value to the farming community. It certainly entails a large 

 amount of labour, but as it is distinctly educative and helpful in character, it must re- 

 ceive attention, though at times it undoubtedly interferes with the research work in 

 progress. If, however, all branches of the work of the Chemical Division are to be 

 maintained, further laboratory assistance will be necessary. 



The following table states the number of samples received, their nature, the pro- 

 vince from which they come, and those still awaiting examination.
