starting your lime to slake and adding this sulfur in the 

 form of a paste. Don't try to get all the heat of the lime, 

 especially if it is a hot lime. Just try to get up a kind of 

 whitewash out of your lime and sulfur. After it is thor- 

 oughly slaked it is drowned with cold water, so that we 

 say that all it is really is whitewash. This requires extra 

 good agitation. I have seen in the bottom of a barrel this 

 stutf pretty near as hard as cement, where they had to 

 take a sharp instrument to get it out, so that it requires 

 extremely good agitation if you are going to apply it to 

 peaches. This is applied again three weeks afterwards, 

 and at this time, if you have any curculio add two or three 

 pounds of arsenate of lead. The last application of this 

 same spray of eight pounds of lime and eight pounds of sul- 

 fur is made about a month before the peach ripens. I know 

 that year before last we were a little late on our spraying and 

 we applied it only about three weeks before they ripened and 

 they looked as if they had all been whitewashed. The peach- 

 es were all white with it but there wasn't very much com- 

 plaint, there wasn't any complaint, in fact, and they kept 

 fine; but I wouldn't advise it so late as that; it shouldn't be 

 applied within four weeks of the ripening, because it forms 

 a white coating and is hard looking. You can add the ar- 

 senate of lead with this material at any time. This is not 

 harmful to the leaves of the peach trees nor to the blossoms. 



Mr. Morse. Could the concentrated lime-sulfur be used 

 on the peaches? 



Mr. Henry. I was just coming to that. "We tried that 

 in connection with the Connecticut Experiment Station, and 

 I guess we had a dozen different mixtures there last year. 

 We tried everything we ever heard and a lot that nobody 

 else ever did, I guess, and all of them hurt the peaches. We 

 used a concentrated mixture as weak as 1 to 150 and with 

 us it simply seared the leaves and the peaches dropped on 

 the ground within three or four days after. They took all 

 the peaches off the trees, and they were a heavy load. Some 

 o'her people have used some strengths and it didn't seem to 

 do any damage with them. But you can use the self-boiled 

 lime-sulfur and I will guarantee it won't hurt, either with or 

 without the arsenate of lead. But be very careful how you 

 use the concentrated mixture on peaches. Use it on one or 

 two trees and if it doesn't hurt them go ahead; but we 

 haven't been successful with it and have found that it 

 did very severe damage on ours.
