PROF. LIPMAN: The injury of course is probably of a 

 fungous character, and we know that barley, oats or wheat 

 would be apt to act in the same way when it is dry, warm 

 weather. The rust and the mildews are, as we know, apt to 

 cause serious injury. We find that to be a great difficulty 

 in our experimental work in the green-house where we use 

 cats, wheat or barley, their rusting. When that condition 

 is very bad, I imagine that buckwheat might be substituted 

 and would answer the purpose, and if that is not satisfactory, 

 r suppose Kaffir corn or sorghum might do. Sorghum of 

 course is much ranker and we must realize that we don't 

 want too much vegetable matter or we might dry the soil 

 out too much for the use of the trees. 



Ism. WINSOR: Could we help by the use of formalde- 

 hyde? 



PROF. LIPMAN: Yes, if the spores of the fmigus are 

 carried on the seed, which is apt to be the case, then the 

 treatment of the oats or barley with formaldehyde would 

 help matters very greatly. 



A :\IEMBER: What are the conditions of using formal- 

 dehyde in that instance? IIow do you use it? 



THE CHAIRMAN : If you send over to the office, Room 

 136, State House, I think we can give you a pamphlet on 

 that subject. 



MR. HUSTON OF NEW YORK : I really have a sort of 

 a question in regard to the title of the subject here, the ex- 

 pression that on account of the high prices of fertilizers the 

 matter is of a good deal of 'importance. I think it is not 

 unfair to call attention to the fact that the different ingre- 

 dients entering into the commercial fertilizers have changed 

 prices, but from quite different reasons. Your ammoniates 

 have always been sold on the basis of supply and demand. 

 Now nitrate of soda has gone up quite materially and freight 

 has gone up very much. The demand has gone up very 

 much; the other ammoniates go along with it, so that is 

 nothing unusual. Yonr phosphoric acid proposition is quite 

 unique; phosphate rock has gone down, but sulfuric acid
