setts Agricultural Experiment Station to do is sure to increase. 

 This line of work is liiglilj important and useful, and it would 

 seem to be the part of wisdom to make special provision for it 

 in order that station workers may be more free to devote them- 

 selves to investigation. 



Lectures and Demonstrations. 



Members of the station staff have been frequently called upon 

 during the past year to deliver public lectures and to conduct 

 demonstrations. The number of lectures and demonstrations 

 given during the year was 56, while a large number of invita- 

 tions to accept such engagements were, of necessity, declined. 

 Work of this character makes heavy inroads upon the time of 

 station workers, for it involves in the long run the use of much 

 time in travel and in preparation. In so far, however, as sta- 

 tion men have special knowledge of certain subjects, it seems 

 desirable that they should address a reasonable number of im- 

 portant meetings, since in this way the results of the work of the 

 station are carried to the public, while the lecturer on his part 

 is brought into closer and wholesome touch with the public 

 which he aims to serve. 



M1SCEL1.ANEOUS Analyses. 



The chemist reports the usual large number of miscellaneous 

 analyses. Work of this character done during the year may be 

 summarized as follows : — 



Water, 99 



Milk, . . ' 389 



Cream, 2,933 



Feed stuffs, 98 



Tertilizeis and fertilizer materials, .... 234 



Soils, 42 



Miscellaneous substances, 45 



This summary includes simply the analytical work carried 

 out for individuals. The results of these analyses are of interest 

 in most cases only to the persons sending in the material. It is 

 recognized that this work has its value ; but investigational work
