No. 7. DEPARTMENT OF AGRICULTURE. 5S7 



Shortly after the trees are done blossoming we spray them again. 



This time using a modified Bordeaux with the Ferro-Cyanide, 

 (Yellow Prussiate of potash), test and using for European plums, 8 

 ibs, vitrol to the hundred gallons with ten to twelve lbs. lime, and 

 six lbs. arsenate of lead. For peach and Japan plums we use two 

 to three lbs. vitrol, eight to ten lbs. lime and four to six lbs. arsenate 

 of lead. Should rains be frequent we repeat this in a week or ten 

 days with three to four lbs. of arsenate of lead instead of six. After 

 this you will probably find it necessary to use a dilute vitriol water; 

 sulphate of copper one or two pounds, water one hundred gal- 

 lons, or you can use the Ammoniacal solution of copper carbonate. 



We use the weak vitriol water on most all fruits at this time. 

 The danger in using lime is the coloring of the fruits. If you have 

 done your duty up to this time you will not have any considerable 

 amount of rot develop during the ripening of your fruits and this 

 weak vitrol water will keep your orchards healthy. 



We use Spraymotor Nozzles. We have found them satisfactory, 

 make a fog or mist and they do not clog when used in connection 

 with our strainer or separator. We use six to twelve nozzles in 

 combination. We use the Spraymotor cut off valve. W^e are not 

 cranks on this and are not interested in the sale of them, directly 

 or indirectly, or are any of our friends interested in a spray nozzle, 

 but in our business we find it one of the best nozzles we can use. 



(Exhibits spraying apparatus). In order to start properly in the 

 spring we want to make it as easy as we can. These are the 

 Spraymotor nozzles we use. We like them because they throw a 

 fine spray and don't wear out very readily. I mean by that, that 

 the hole does not get large and thus make them useless. I want to 

 use a dense spray. This is the smallest cluster and we use them 

 up to a sixteen cluster. Then we want a cut off. The ordinary 

 cut off is this kind (holding it up). And we said some things that 

 came very near to being profanity in the use of that. We have 

 men depending on our expedition at that time and we could not stop 

 it leaking and it drenched those men and therefore is not satis- 

 factory so we have discarded it and come to this (holding up the 

 object). This is the cut off" we use now. There is no drip from it. 

 There may be a drip from the cluster, but we have an inverted cup 

 on the rod under the cluster of nozzles, and whenever there is any 

 drip from these clusters it runs out here and drops down and don't 

 drop down on our men. W"e find it is a good thing. We have tried 

 all kinds of nozzles and after a great deal of experience have 

 adopted these nozzles. In large lots you can get them at quite a 

 large reduction. 



Now then we come to another matter, that is we had trouble with 

 these nozzles. They threw rather a fine stream and once in a while 

 they would clog. We then used tfeis separator or strainer. I will 

 unscrew one if anyone wishes to see the construction. While going 

 througli the orchard we were bothered so by clogging that we put on 

 this other strainer. This screws into your air chamber, or below your 

 air chamber and the liquid is forced through here and up through 

 here; it is usually shut off like that (illustrating), or opened by this 

 valve to clean itself if it gets clogged. This union here I will take 

 pff; that is pretty well worn out; Now, here, this has been screwed
