 in the soil ; turpentine mixed with lime or sand, placed round plants 

 on the surface of the soil. 



As a combined insecticide and fungicide : resin-Bordeaux mixture, 

 at the rate of 2 U.S. gals, resin-lye mixture and 48 gals. Bordeaux 

 mixture ; Paris green or lead arsenate may be added if desired. 



As adhesives : resin-lye mixture, consisting of 5 lb. resin, 1 lb.

Lime-sulphur from the formula, quick lime 1 lb., sulphur 21b., 

 water 1 (U.S.) gallon, boiled together for three-quarters of an hour, is 

 recommended and practical information as to its preparation is given ; 

 the method of preparation of self-boiled lime-sulphur from lime 8 lb., 

 flowers of sulphur 8 lb., water 50 (U.S.) gallons is given with a warning 

 as to the indiscriminate use of the commercial " dry sulphur compound," 

 which is more expensive than the home-boiled and liable to cause 

 serious scorching. The sediment resulting from the preparation of 

 lime-sulphur is valuable in several ways : — (1) in counteracting soil 

 acidity and thereby improving the growth of leguminous crops ; 

 (2) as a preventive of club root and black rot of cabbage and as a tonic 

 for orchard trees ; (3) as an addition to dormant spraying fluids, 

 rendering them more adhesive ; from 2 to 5 gals, may be added to 

 50 gals, of spray ; (4) as a wash to prevent borers of trees ; from 

 I to 1 pt. should be applied to each tree, and against the peach borer 

 \Anarsia lineatella] three or four apphcations during the summer are 

 recommended. The results of this use of the sediment are said to be 

 highly satisfactory.
