(7) Resin soap for Bordeaux mixture and for resin wash, — In the 
course of work in Florida. Mr. W. T. Swingle, one of my assistants, lias 
found that a clear resinous solution may be very quickly made as fol- 
lows: 
Resin. 2 parts. 
Crystallized sal soda, 1 part. 
Melt together and add 4 parts of water. 
This forms a stock solution of a beautiful clear brown color. I have 
ased it. at Mr. Swingle's suggestion, in connection with Bordeaux mix- 
ture to increase the wetting power of the latter, and find it just as 
effective and much cheaper than ivory soap or whale-oil soap. The com- 
pound costs about \h cents per pound, while ivory soap can not be 
bought for less than 16 cents and whale-oil soap for less than 8 cents per 
pound. It is probable that this preparation might prove equally as 
valuable as the ordinary resin washes as an insecticide, and its use as 
such is therefore suggested. 
(8) Sulphur compounds. — A number of the sulphur compounds have 
proved of value as insecticides and fungicides. They are among the 
oldest preparations in use. especially as fungicides. Among those gener- 
ally recommended are potassium sulphide, eau grison. and the sulphur, 
lime, and salt mixture. Potassium sulphide is not now generally used, 
as it is likely to injure the plants. The sulphur, lime, and salt com- 
pound is extensively used on the Pacific coast for the San Jose scale. 
Mr. Pierce, our agent in California, lias also found that this preparation 
will largely prevent peach curl, if properly applied. The eau grison and 
the sulphur, lime, and salt mixture are both troublesome to make, as 
it is necessary to boil together the ingredients of each for several hours. 
Messrs. Swingle and Webber, in the course of their investigations 
upon the diseases of citrus fruits, have experimented with a number of 
sulphur compounds, in the hope of obtaining one that can be made 
cheaply and without the long tedious boiling process. It is believed 
that this has been accomplished, but as there are some points in con- 
nection with the work that yet remain to be settled, it is thought best 
not to give the formulas in full. Suffice it to say that compounds which 
appear to be as valuable as any of the old ones, and which can be pre- 
pared in a few minutes, have been obtained at a cost not exceeding 
one-fourth of a cent per gallon. 
Mr. Galloway's paper was accompanied by the exhibition of a large 
series of vials, illustrating the various insecticide mixtures and combi- 
nations described by the author. Some of. the mixtures were experi- 
mentally made on a small scale, to illustrate the characteristic reactions 
which accompany the combining of the different elements. In the 
course of the examination of the specimens and the discussion which 
followed, it was pointed out that the kerosene mixtures were not as
