Lime dusted on the leaves of plants lia1)le to be eaten 

 by insects is often found useful in the gardens. It is 

 very commonly used to prevent the gnawing of flea beetles 

 and the striped cucumber beetle. Bi-sulphide of carbon and 

 cyanide of potassium are powerful insecticides, but the 

 inflammability of the former and deadly poisonous properties 

 of the latter make their use extremely dangerous. There 

 are many other preparations used for insecticidal purposes, 

 but want of space will prevent further enumeration. 



Spraying Machinery. 

 Within the last ten years a large number of spraying out- 

 fits have been placed upon the market. They are of all 

 shapes and sizes, and suitable for a great man}' purposes. 

 The main points of a good machine are that the pump shall 

 be durable, work easily and throw a forcible stream ; and 

 that the nozzle shall throw a fine spray a consideral^le dis- 

 tance, and be so constructed that the size and quality of the 

 stream may be regulated at the will of the operator. It is 

 better, and w^here the copper fungicides are used is essential, 

 that the parts touched by the liquid be made of brass (Prof. 

 C. M. Weed). In case only a few trees are to be sprayed, 

 a cheap hand pump will frequently do very well. Some 

 form of these can be obtained at almost any hardware store. 

 Among the numerous manufacturers of spraying machinery 

 may be mentioned the following, from whom no doubt upon*

 Field Force Pump Company, Lockport, K. Y. ; Gould's

Spraying with Arsenites. 

 " The spraying with London purple or Paris green should 

 be done soon after the fruit has ' set ', and a second spray- 

 ing should follow for late apples, in from two to three 

 weeks. One spraying should suffice for early fruit. Never 

 spray with Paris green or London purple late in the season,
