mending dilute Bordeaux mixture (4 pounds of sulphate of copper and 4 pounds of lime in 50 
gallons of water). Paris green may be used with the Bordeaux mixture as an insecti¬ 
cide. (J.F.J.)

Gives details of experiments with carbonate of copper, sulphate of copper, hydrate of 
copper, borate of copper, and chloride of copper, all used in combination with arsenites. 
The results of the experiments are briefly as follows: The effect of ammoniacal carbonate 
of copper as a fungicide is not lessened when Paris green or London purple is added, and 
gave bet ter results with H ounces in 1 pint of ammonia than double the quantity in 22 gallons 
of water; but the combinations have a caustic effect on the foliage of most plants. Sulphate 
of copper with Paris green and London purple formed an unsatisfactory combination: 
hydrate of copper alone is not as effective as when applied with Bordeaux mixture, 
although it did little injury to the foliage; borate of copper lias little fungicidal action and in 
combination with arsenites is caustic; chloride of copper gave better results than the Bor¬ 
deaux mixture, but it must be weak (U ounces in 22 gallons of water injured the foliage of 
apple and peach trees). Mention is made of experiments in other places. In a note (p. 338) 
the formula; for Bordeaux mixture and ammoniacal carbonate of copper are given. The 
only successful combination yet found is with Bordeaux mixture and the arsenites. With 
ammoniacal carbonate and the arsenites the foliage is usually seriously injured (see also 
Exp. Sta. Rec., vol. nr, Washington, Mar., 1892, pp. 524-526). (J. F. J.)

A report of work done at the station, at North boro, and by various individuals under 
the direction of the horticulturist. The four fungicides used were Bordeaux mixture, 
ammoniacal carbonate of copper, sulphate of copper, and sulphate of iron. Short descriptions 
are given of the following diseases: Apple scab, pear leaf-blight, plum leaf-blight or shot- 
hole fungus, brown fruit rot, powdery mildew and black rot of the grape, potato rot, and 
black wart of plum and cherry. Experiments were made to prevent all of these, with gen¬ 
erally good results. Paris green was used in combination with the Bordeaux mixture. The 
reports of the volunteer observers vary, but they note generally favorable results. Dr. 
Jabez Fisher describes a syringe for spraying, called by him the “Hydrospray.” He also 
records good results in combating tomato rot by the use of 1 pound of copper sulphate in 1,090 
gallons of water. The foliage was not injured and the spread of the fungus was checked. 
At Northboro, peach, plum, pear, and apple trees, grapevines, and black raspberries were 
treated. Bordeaux mixture injured the peach foliage, but ammoniacal solution checked the 
rot. Anthracnose of raspberries was successfully treated with Bordeaux mixture and copper 
sulphate, and potatoes were treated with Bordeaux mixture and Paris green wit h good results. 
It was also found that black knot of the plum could be destroyed by painting with “kero¬ 
sene paste,” made by mixing ordinary kerosene with French yellow or any other dry pig¬ 
ment. Crude petroleum would do equally well if thick enough not to spread over the limb 
(see Exp. Sta. Rec., vol. in, July, 1892. pp. 864-866). (J. F. J.)
