in early spring of underbrush and weeds. But in regions where wild 
strawberry and blackberry, Potentilla, and red-bud grow in such profu- 
sion as in the neighborhood of Washington, D. C., it would appear that 
little benefit would accrue from such a course. 
Unsuccessful remedies. —A number of remedies that have been tried 
are found to be unsatisfactory. Capturing the beetles with a sweep-net 
has been suggested, but this species is not readily taken by this method. 
Among the various substances that have been experimented with and 
not found satisfactory, either as deterrents or insecticides, may be men- 
tioned: lime, ashes, dissolved bone, ammonia in the form of hen manure, 
kerosene and plaster, Paris green and plaster, a mixture of © tobacco 
dust, lime, Paris green and coal oil,’’ pyrethrum, whale-oil soap, and a 
solution of sulphate of copper and lime. Even kerosene emulsion has 
been only partially successful. Pyrethrum has little or no effect when 
used in the open field. 
A good repellent needed.—From the manner of the insect’s work it is 
obvious that whatever is used must be of rapid action. What is most 
wanted is a good repellent. For this purpose we would advise a trial 
with a spray of crude carbolic acid, used in the proportion of 1 part to 
100 of water. This preparation has been reported a successful protec- 
tion against the rose-chafer in vineyards. 
One of our correspondents has reported some success with Bordeaux 
mixture, and as this substance has been found effective against other 
species of beetles where Paris green failed it is well worthy of further 
trial. It affords protection to plants by rendering the foliage distasteful 
to the insects. Bordeaux mixture has the advantage of being a fungi- 
cide, for which purpose it is mostly used, and should the plants be also 
affected with blight, as is so often the case, it will fulfill a double pur- 
pose. In case Paris green is used the Bordeaux mixture should be 
employed as a diluent in the place of lime and water in the preparation 
of this arsenical. 
Arsenical spraying.—The arsenites, as already stated, can not be 
depended upon to produce as good results as against leaf-feeding insects, 
for the reason that the adult weevils do not feed on the foliage, and 
hence may be reached only when they feed on the open blossoms or cut 
through the corolla of the buds or flower-stems during oviposition. The 
larvee can not be affected at all by this or any other known insecticide. 
The arsenites do not commend themselves to the average strawberry 
erower because of the fear of poisoning the consumer, but experiment 
has shown that there is not the slightest possibility of the poison remain- 
ing upon the fruit, since the spray to have any effect on the weevil must 
be apphed while the plants are in bud or blossom, the last application 
being made two or three weeks before the first berries ripen. One of 
our correspondents has met with sufficient success, however, to justify 
further tests. 
Either Paris green or London purple may be used at the rate of 1 pound 
of the poison to 100 gallons of water, and the arsenite of lead at the rate 
of 1 pound to 25 gallons of water. In their preparation it will be advisa- 
ble to use Bordeaux mixture as a diluent, particularly if blight is pres- 
ent in the beds. 
It should also be remembered that the arsenicals act with good 
success on other insects that might be present on the vines, for exam-
