No. 6. DEPARTMENT OF AGRICULTURE. 577 



at once, in hv^ hoj»sheads or tanks vou ought not to boil less than 

 two hours, perhaps three, and it is advisable to have a steam plant. 

 A man, who is doing as much work as Dr. Funk, needs a larger 

 ai)I)aratus than where there is a small requirement. To boil a large 

 quantit}^ at one time you cannot get it properly made under two 

 hours and in one boiling an hour or hour and a half is not suflQcient. 



The PRESIDENT: The proper time then is to boil the ingredients 

 two hours? 



PROF. MARLATT: It is. Of course if you have a small kettle, 

 say, holding ten gallons and wish to spray only that quantity, if 

 you have trees in your lot, you can get the combination in twenty 

 minutes. The test of the boiling is the combination. If your sul- 

 phur has been all converted and thoroughly mixed with the other 

 ingredients, when you dip it up your boiling is sufficient. You don't 

 have to continue it until every bit of sulphur is gone. 



The PRESIDENT: I think there are very few farmers who have 

 a steam apparatus about their farms; most of them have not. If 

 they have to depend on this remedy and the process of boiling 

 which has been described they will have to boil in some other way. 

 Can it be boiled in kettles? 



MR. MARLATT: Yes, sir; it can be boiled in kettles. 

 MR. LEDY: How do you mix it? 



PROF. MARLATT: It is advisable to mix the sulphur in the 

 water first because it is fine powder and if you don't it will mix 

 in lumps. Mix the sulphur in a paste and put the lime in a kettle 

 and enough water to slake it, a fresh stone lime, and start the 

 fire at once and you get the heat from the slaking lime and put 

 the salt in at the same time, or, afterwards if vou choose. Just

as well put it in, all at the same time, and let it boil the time 

 required. If you have a large tank it is well to have the whole 

 amount of water at the start, but it is exceedingly more convenient 

 to start with a third or half of the water and fill it out afterwards. 



A Member: In applying strong solutions are not peach trees more 

 likely to be killed than apple trees, quince trees or pear trees? 



PROF. MARLATT: You are quite right. 



A Member: It has been my experience. 



PROF. MARLATT: In fact most any one can spray apple or 

 plum trees but the peach tree is much more tender. 



A Member: Should there not be a warning about mixtures on 

 account of not stirring them properly? I had a friend who neg-
