No. 4.] SPRAYING PUMPS. 119 



position so that it would not fall over the side of the cart, 

 but it is a very serviceable machine. The knapsack pump 

 can be used only in case of small trees and clumps where 

 the larger pump cannot be driven, and nothing higher than 

 fifteen or twenty feet can be reached with it. We have ex- 

 perimented with a number of pumps, and we find these 

 among the best. There are some features in these that we 

 do not find in any other. Here is the adjustable gem nozzle, 

 which is very serviceable where a stream is to be carried a 

 long distance to very high trees. The stream breaks at the 

 end, and does not give the best results. The Yermorel 

 nozzle is the best, because the stream comes out in the form 

 of a very fine mist. We shall try to be at the spraying ap- 

 paratus and evaporators so as to answer any questions which 

 may be asked in the intervals of the meetings. 



Mr. George M. Whitaker, assistant executive ofiicer of 

 the State Dairy Bureau, stated that no samples of milk had 

 been furnished with which to use the Babcock milk tester, 

 but that he expected to have twelve or fifteen samples the 

 following morning, and invited any of the audience who de- 

 sired to have milk tested for percentages of fat to bring the 

 samples to him, stating that it would be better to have the 

 milk from difterent breeds brought in separately, not mixed. 



Secretary Sessions. At the request of the vice-president 

 of the Board, I will announce that Mr. E. W. Wood, chair- 

 man of the executive committee, will preside this afternoon. 



The Chairman. Ah you remember, the subject of the 

 lecture this morning was a consideration of how to profitably 

 and economically feed the soil. This afternoon we are to 

 consider how to feed the products of the soil most economi- 

 cally and practically. The committee has secured the ser- 

 vice of a gentleman from across the imaginary line which 

 we hope ere long will be obliterated, and I have the pleasure 

 of introducing to you Professor Robertson of Ottawa, Can.
