oil) ; Yz lb. soap, i gal. water, 2 gals, kerosene. 

 Immediately place in a pail and churn or pump until 

 a thick, lathery cream results. This is the stock 

 solution : for use, dilute with five to fifteen times 

 as much water, according to purpose applied for — 

 on dormant fruit trees, 5 to 7 times; on foliage, 

 10 or even 15. 



Of the poisons for eating-insects, arsenate of lead 

 is the best for use in the fruit orchard, because it 

 will not burn the foliage as Paris green is apt to 

 do, and because it stays on longer. It can be used 

 in Bordeaux and lime-sulphur mixtures, thus kill- 

 ing two bugs with one spray. It comes usually in 

 the form of a paste — though there is now a brand 

 in powder form (which I have not yet tried). This 

 should be worked up with the fingers (it is not 

 poison to touch) or a small wooden paddle, until 

 thoroughly mixed, in a small quantity of water and 

 then strained into the sprayer. Use, of the paste 

 forms, from one-fourth to one lb. in 20 gals, clear 

 water. 



Paris green is the old standard. With a modern 

 duster it may be blown on pure without burning, if 

 carefully done. Applied thus it should be put on 

 during a still morning, before the dew goes. It is 

 safer to use as a spray, first making a paste with a 

 small quantity of water, and then adding balance 

 of water. Keep constantly stirred while spraying.
