the orchard had been sprayed with Bordeaux mixture* for 

 various fungous diseases. After the trees were " wormed " 

 the rather thick and sticky " tailings " or sediment, left from 

 this Bordeaux mixture, was painted over the trunks and lower 

 branches of the trees. This might have been improved some- 

 what by the addition of a small amount of Paris green. The 

 trunks were painted to about two inches below the surface of 

 the ground and the earth mounded back as usual. On March 

 26, 1897, the orchard was again gone over and carefully 

 "wormed," but this time the two hundred and twenty trees 

 yielded but forty worms, and eight of these worms came from 

 two trees, which had evidently not been properly treated the 

 preceding year. The treatment was considered successful — 

 complete extermination the first year was not expected. 



A substance called "Dendrolene" or " Insect Lime," and 

 which has something the appearan(5e and consistency of axle 

 grease, has been used for this and similar purposes, as a coat- 

 ing for fruit tree trunks. It has been somewhat widely 

 recommended through bulletins from various sources, more 

 especially those from New Jersey and the Department of Ag- 

 riculture. Its use may have been attended with success in 

 New Jersey, but our tests of it here have resulted most disas- 

 trously. On April 5, Prof. Earle had it applied in the pre- 

 scribed manner on several mature peach and plum trees. It 

 killed about one-half of these outright and very seriously in- 

 jured the remainder. In consequence of these results we do 

 not recommend its use in Alabama. 



*Bordeaux mixture, much used for various rusts, leaf-spots, or other 

 fungous diseases. Is prepared as follows: Thoroughly dissolve in sepa- 

 rate receptacles, each with 25 gals, water, 6 lbs. copper sulphate and C 

 lbs. /r'^s/i lime. Then pour together in a third vessel. Stock solutions 

 of each may ba kept on hand, but should not be mixed until wanted 

 for use.
