these washes leave nothing to be desired. In all cases the most 

 careful search over the sprayed trees has failed to show a living 

 scale." These are known as " winter washes," since they can 

 only be used during the winter without serious injury to the trees. 

 The winter resin wash mentioned above is composed of resin, one 

 hundred and twenty pounds ; caustic soda, thirty pounds ; fish oil, 

 fifteen pints ; water sufficient to make one hundred gallons. The 

 resin and soda are broken up and placed in a large kettle with the 

 oil and sufficient water to cover them ; the whole is then boiled 

 for several hours, or until the compound will properly mix in 

 water without breaking up into yellowish flakes. Experiments 

 thus far made with applications during the summer have failed to 

 give a substance that will destroy all of the insects. As good 

 results have been obtained from the use of ordinary kerosene 

 emulsion as from any other substance. It was found advisable, 

 however, to repeat the spraying at intervals of about a week, as 

 the young are brought forth in succession during the season. 

 Kerosene emulsion is composed of kerosene oil, two gallons ; com- 

 mon soap, one-half pound ; water, one gallon. Cut up the soap 

 and boil it in the water till it is all dissolved, then add it, boiling, 

 hot, to the oil, and churn it briskly for five minutes or more with a 

 spraying or force pump. When required for use mix thoroughly 

 one part of the above emulsion with nine parts of water and spray 

 the trees with it. In spraying peach trees, however, it is recom- 

 mended, because of their liability to injury, to mix one part of the 

 emulsion with fifteen parts of water. The emulsion will dissolve 

 more readily if hot water be used. 



Legislation. 

 It is strongly recommended by some entomologists to have laws 

 passed requiring nurserymen and other dealers to guarantee their 

 stock free from the San Jose scale ; but I am free to confess that 

 I feel very doubtful about this matter. It seems to me that the 

 fear of loss of trade will be a greater incentive to send out only 

 uninfested stock than the fear of any amount of legislation.
