tion in regard to the ordinary limoid and the superfine Hmoid, 

 to please my friend, Mr. SkiHman from New Jersey. He 

 wanted that point brought up, and while I don't know posi- 

 tively that to be the fact, yet I understood the superfine 

 was made in the way I have stated. 



A Member: Have you ever used any of this "Scalecide" 

 that is advertised quite largely? 



Mr. Derby : No ; I understood a day or two ago that the 

 strength of "scalecide" that is ordinarily recommended has been 

 almost, but not quite a failure, but double that strength has 

 given good results, and that makes it quite expensive. 



A Member: Laying aside any prejudice we have for oil 

 and petroleum, will not oil carry the sulphur where the lime 

 and sulphur will not, on the bark of an apple tree ; the con- 

 ditions are different than on a peach tree, and it will not 

 penetrate on an apple tree where it does on a peach tree. 



Mr. Derby : There is no question but what the oil penetrates 

 and spreads as nothing else does, and the union of the oil 

 and sulphur mixture has seemed to us to be ideal. 



Secretary Miles: There is a question on our list of ques- 

 tions — number 12 — which Mr. Derby would be a good one 

 to answer, "Can we afford not to spray for apple scab and 

 coddling moth?" 



Mr. Derby : I had a little row of Winesap applies, and I 

 had a few Strawberry apples, eight trees, that were taken 

 eleven years ago as a basis of some experiment work that the 

 Delaware experiment station were going to do, for the rea- 

 son that for two years we had those trees covered with a 

 crop, and yet we didn't market one single apple from either 

 the Winesap or the Strawberry. Now, the first season we 

 gave those trees five sprayings with bordeaux and arsenic, 

 reserving two trees unsprayed. For six years that work was 

 carried out. We divided all the apples that came oft" of these 

 trees, whether picked off or fallen oft', into three classes — 

 so scabby as to be worthless, scabby enough so they would do, 

 and those entirely free from scab. I have the figures out 

 home, and I intended to put 'them in my pocket, but I 

 have forgotten them. In six years oft" the Winesaps, the five 

 trees that were sprayed for scab only, we picked six crops
