constantly covered with a thin coating of oil, or the buds and blossoms 
with the arsenical. For example, if the variety of berry to be treated 
begins to bloom April 27, it might be sprayed on the 24th or 25th, again 
on the 29th or 30th, and a third time, say May 5. It is doubtful if a 
fourth application would be profitable except in the event of rain or heavy 
dew fall after spraying, as the chief damage is done during the first two 
weeks of blooming. The finest possible mist-like spray should be 
obtained and applied lightly, in such a manner that it will adhere to the 
plants, and not form globules and roll off to the ground. 
In the use of the kerosene emulsion the greatest care should be 
observed, first, that it be properly prepared, second ; that it be not 
applied in too large quantity. In its preparation the usual formula is 
used, viz, 2 parts kerosene, or coal oil, to 1 part soap solution or milk. 
For use on strawberry vines a 10-per cent solution, made by diluting 
with 9 parts water, will probably give the best results. 
Either Paris green or London purple may be used on strawberry in 
the same proportion as on apple, viz, 1 pound of the poison to 150 gal- 
lons of water. 
The best form of apparatus for spraying garden plants is the knap- 
sack sprayer, fitted with the finest Vermorel spray-nozzle. 
In case the plants should also be affected with blight the Bordeaux 
mixture may be employed as a diluent, instead of lime and water, with 
either the emulsion or the arsenites and in the same proportion. 
Full directions for the preparation and application of these remedies 
are given in Farmer's Bulletin No. 19 of this Department, and therefore 
need not be repeated here. 
It should also be remembered that the arsenicals will act with good 
success on other injurious insects that might be present on the vines, 
e. </., the strawberry slugs, the leaf-rollers, and the adults of the root- 
borers, while the emulsion would prove valuable against the strawberry 
plant louse. 
On Covering Beds as a Preventive. — Several conditions have operated 
against the adoption of a covering for the beds: A disinclination on 
the part of the grower to incur what seemed an extra expense — although 
this would be amply repaid by the protection against frost and the 
earlier harvesting of the crop— and a general disposition to u take the 
chances" of the insect being again injurious. Again, there is often 
great difficulty in inducing a farmer to adopt remedial measures except 
at the time when the damage is most apparent, and this is, of course, too 
late for successful treatment of a species like the one under considera- 
tion. Another reason assigned for failure to employ precautionary 
measures was a fear that the insect hibernated in the beds. Now, 
while a few individuals may do so, particularly in old beds that have 
become choked up with grass and weeds, the majority, in all probability, 
seek more sheltered retreats. In conversation on the subject in 1892 
with some of our local growers I expressed the opinion that the new
