170 MINNESOTA STATE HORTICULTURAL SOCIETY. 



Mr. E. G. E. Reel : Did I understand you to say that one pound 

 of lime was sufficient to neutralize the effect of one pound of Paris 

 green ? 



Prof. Snyder : Yes, it is. It depends largely upon the lime. 



Mr. Reel : More will do no harm ? 



Prof. Snyder : It will do no harm, but it is apt to give a little 

 trouble in the way of clogging the spraying machine. 



Mr. R. A. Schutz : It would not be safe to turn the hogs 

 into an orchard that has been sprayed ? 



Prof. Snyder : Not immediately after ; yet there is little danger 

 from it. But it is possible that the machine has not been working 

 perfectly, and there is a good deal of dripping in one spot, but 

 where it is evenly spread the danger is very slight. I would first 

 look about the orchard to see whether there is any undue amount of 

 the mixture spilled before turning in the hogs. 



Mr. Schutz : It would not do to have them in at the time of 

 spraying ? 



Prof. Snyder : It would be better not. 



Prof. F. L. Washburn : Dr. Cook experimented to see what 

 Paris green would do. He made a Paris green solution and allowed 

 it to drip on the grass. He used a strong solution, one pound of 

 Paris green to 100 gallons of water, and then he turned his horse in 

 on the grass without any injury. I think, Mr. President, it is 

 perfectly safe to turn stock into the pasture after using Paris green. 

 A gentleman downstairs told me he sprayed his apple trees with 

 arsenic and lost all his turkeys and lambs. I think there is no danger 

 whatever with Paris green. 



Prof. Snyder : It is true if the spray is evenly applied, but there 

 is a possibility of the machinery not being in perfect working order 

 and getting too much at one place. 



Mr. Brackett : In Iowa they are using arsenic. The arsenic is 

 boiled with sal soda, and it makes a solution that does not settle. 

 They are using that most successfully. 



Prof. Snyder: Yes, and there are two or three others, but I 

 thought it best to keep to the Bordeaux mixture, as our people want 

 as inexpensive a spray as possible, and I think the Bordeaux is a 

 little better on that account. However, the other spray is a very 

 good one. 



Mr, J. F. Benjamin : Is there any possibility of poisoning a hog 

 by any mixture? 



Prof. Snyder : I do not know about the hog, but cattle are quite 

 susceptible.
