Summer Meeting. 121 



Manufacturing Co. of Kansas City, Mo., with practically a perfect 

 crop, no scab, and not 5 per cent with worms. 



I run my machine with mule power, having it geared with a 

 sprocket wheel on the large wheel of the wagon. But little labor 

 is required in operating the machine — a small boy to drive, a seat 

 in the back end of the wagon to control the pipe. Can spray 50 

 acres of the large trees in a day, doing thorough work. Have 

 sprayed eight times, using $100.00 worth of material, allowing 

 $40.00 for eight days' work, making $140.00; sprayed 4,000 trees; 

 average cost per tree for material and labor, 31/2 cents. 



WHEN TO SPRAY AND WHAT TO USE. 



For fungous diseases just before the bloom opens, use the sul- 

 phate of copper, sulphur and lime dust. After bloom drops, with 

 general formula, consisting of lime dust, sulphate of copper, sul- 

 phur and Paris green, until the first of June, then with the insect- 

 icide, lime dust and Paris green; spray up to the first of August. 

 If you want to succeed, spraying three or four times is not enough. 

 Stand guard with your mixture until the enemy retreats. 



The Bordeaux mixture is to destroy fungous diseases. In liquid 

 form, consisting of water and sulphate of copper, you have nothing 

 in the compond to kill fungus but the copper. In the dust you 

 have three things, lime dust, sulphate of copper and sulphur. All 

 three are good fungicides. The liquid has an imperfect carrier ; the 

 dust has a perfect distribution — a most necessary thing in the 

 application of the mixture. 



Spore life is not confined to the tree, but is on the ground and 

 floating in the air, so say our scientific professors. If this be true, 

 then you want to distribute your mixture, so as to bring it in con- 

 tact with the greatest number. Spore life is destroyed by the 

 caustic elements of the mixture. 



In the dust you are not limited in the strength of the mixture. 

 You are in the liquid. Pure sulphate of copper is conveyed to the 

 tree not impaired by any chemical action in preparation. In the 

 dust the mixture is ground to a fine powder — every particle of 

 dust has its pro rata of sulphate of copper. Your insecticide in 

 liquid form, limited; in the dust, unlimited. Water, of no value; 

 Lime dust, of great value as a fungicide and insecticide. The caus- 

 tic element of the lime will kill thousands of the codling moths when 

 first hatched out. 



Our critics are driven to the extremity of saying, "Well, it 

 won't stick, it will blow away." I have bio wed out tons of the mix-
