better than lime-snlpliur solution, and for strawberry plants we can use 

 as much as three to five gallons of the lime-sulphur solution to fifty 

 j>allons of water. I have used Bordeaux mixture with splendid success 

 and like it very much, but if I am to judj^e results by a series of exfieri- 

 ments which T have carried out with Bordeaux mixture and lime-sulphur 

 solution, I should choose the lime-sulphur. However, I do not wish to 

 change the mind of anyone who is getting good results with P>(n'deaux 

 mixture. 



For leaf-chewing insects, to my mind, there is nothing better than 

 araenate of lead, and I have used as much as five pounds of arsenate 

 of lead to fifty gallons of water without injury to the foliage. For most 

 of the leaf-chewing insects, one spraying with the arsenate of lead solu- 

 tion will put them where they belong. The leaf-roller is one of the 

 hardest insects tO' control, on account of the cunning they employ 

 to protect themselves by folding the edgesi of the leaf together. This 

 makes it difficult to reach them with the poison. I find that it is abso- 

 lutely neces.sary, when spraying for leaf rollers, to begin the spraying 

 just as soon as the eggs begin to hatch, and during the past year or 

 two I have been using two and one-half pounds of arsenate of lead and 

 one and one-half pints of white arsenic solution to fifty gallons of water. 

 This makes a rank poison, and makes it mighty unpleasant for the 

 pesky little leaf-rollers. 



In preparing arsenate of lead, it is very necessary to pulverize it 

 thoroughly. Put the lead into a two-gallon bucket and pour over it 

 just enough water to moisten, then use a mallet or potato masher for 

 pulverizing. This material dissolves very slowly, and the one preparing 

 it should whirl the potato masher or mallet around the edges of the 

 l)ucket, which will grind the material between the mallet and sides 

 of the bucket, which, of course, will aid in dissolving it. Continue 

 adding water and grinding and })ulverizing until you have a perfect 

 crcamv solution, and when you are through the bucket should be almost 

 full. 



In preparing white arsenic solution, take one pound of the white 

 arsenic, two pounds of sal soda and one gallon of water; boil until all 

 are completely dissolved. AA'hen cool, add one and one-half pints of 

 this solution to the two and one-half pounds of ai-senate of 

 load which you have prepared. Stir these until they are com- 

 jiletely incorporated, and add fifty gallons of water. Although this 

 is a vei"y strong arsenate solution, no grower need hesitate to use it for 

 fear of burning the plants, because the leaf tissues of strawbei*ry plants 

 are very tough and not easily burned by using a strong spray solution 

 I have used this repeatedly without any injurious effect. 



In spraying the fruit bed, the same solution may be used as I have 

 recommended for the young growing plants, but do not spray with the 

 arsenate solution after the fruit is formed. Pyrethrum would be safer 

 at this time. And let me suggest here that it is not necessary^ to spray 

 unless you have something to spray for, and that spraying must be thor- 

 oughly done to get best results. Here is where the perfect mixing 

 comes in again. Spray material poorly mixed will not give the desired 

 results. 



When spraying for fungous troubles, nozzles should be used through
