top of the water, or by pounding the lumps 

 into small bits and dissolving by the use of 

 hot water. This solution attacks metals 

 (except copper) very actively. 



"Lime Paste — Slake three pounds of 

 quicklime with one gallon of water, in the 

 ordinary manner. 



"Mix in Equal Parts — When the lime 

 is cool enough, equal parts of the bluestone 

 solution and the lime paste should be mixed 

 together thoroughly. Mix only enough at 

 one time for a day's use. Apply like 

 whitewash with a brush. The stock blue- 

 stone solution and stock supply of slacked 

 lime can be kept indefinitely if not mixed 

 together, provided w-ater is added from 

 time to time, to keep the solution up to the 

 original volume. 



"If Bordeaux paste is used alone its ap- 

 plication should be repeated every fall." 



POWDERED Bordeaux, which is now 

 made by several manufacturing com- 

 panies, can be used more conveniently. In 

 this form all that is necessary before mak- 

 ing application is to add sufficient water 

 to the powder used to form a reasonably 

 thick paste. This is then applied with a 

 brush to the exposed surface. 



Before making application of the Bor- 

 deaux paste, it will be necessary to remove 

 all dead bark around the edges of the 

 wound, cutting back to live, healthy tissue. 

 All badly damaged branches should be 

 sawed off where they join the trunk and 

 their stumps covered with the paste. The 

 great objection to the use of Bordeaux paste 

 lies in the fact that it flakes off, during 

 the rainy winter especially, and must be 

 renewed every year. To prevent flaking 

 and to make a. paste which is more perma- 

 nent in its nature, different ingredients 

 are being tried with the Bordeaux to im- 

 prove its sticking qualities. Calcium case- 

 inate, at the rate of one-half teaspoon ful 

 to the gallon of Bordeaux paste, is one of 

 these materials used to increase adhesiveness. 

 This treatment is still in the experimental 

 stage and must be watched carefully by 

 anyone applying it. 



Another combination that gives promise 

 is a paint made by using raw linseed oil and 

 powdered Bordeaux. The Bordeaux is 

 slowly sifted into the oil and stirred so as 

 to keep the powder from lumping. When 

 the consistency of heavy paint is reached it 

 is ready for use. This must be applied 

 when the wood is perfectly dry if the 

 treatment is to be successful. Only one 

 coat should be applied in any one season. 



It will be best for the grower to put 

 on some of the linseed oil Bordeaux to a 

 few trees, in comparison with a Bordeaux 

 paste which he might use on the balance of 

 his orchard. In a year or two, it will prob- 

 ably be possible to tell which is the better 

 mixture to use. The main thing to look

 paint is to see whether heart rot develops

Greater Capacity and Pressure 



With a Lighter Engine 



To meet the demand for lighter weight, greater capacity and the 

 higher pressure that is absolutely necessary to produce the desirable 

 "fog spray," several of the leading manufacturers of sprayers have 

 standardized on light weight high grade Cushman Engines for their 



power. 



A Cushman Engine for 



Every Size of Sprayer 



The lj4 H. P. Cushman handles the smaller sprayers of 3 to 

 45^ gallons at 200 to 300 lb. pressure. 



The 4 H. P. Cushman (weight 190 lbs.) is the proper size for 

 the larger triplex orchard sprayers with a capacity of 8 to 10 gallons at 250 to 300 lb. 

 pressure or more. 



The 8 H. P. Double Cylinder Cushman, weighing only 320 lbs., is the ideal engine for the 

 largest orchard and standard shade tree sprayers.

Weighs only 190 lbs.

 less number of parts. 



Rebuild Your Sprayer 

 with the famous Cushman 

 Engine and get more power 

 qnd pressure with less weight. 



Longer Life and More 

 Reliable 



Cushman Engines are light in weight, compactly built 

 and deliver much more power per pound. They are 

 steady in operation and require less attention. They are 

 regularly equipped with auto type Carburetor, sensitive 

 fly ball type Governor, Friction Clutch Pulley for both 

 chain or belt drive, jump spark Ignition, and are forced 

 water-cooled, insuring full power for continuous service 

 under all working conditions. 



They have been successfully used for the difficult "at- 

 tachable power drive" jobs for IS years and are well and 

 favorably known by manufacturers, dealers and repair 

 station mechanics.

 shall tell you what equipment and power is best adapted 

 for your s]trayer.
