in fine sand in a box or flower-pot and bury the latter in the open 
ground until the time for planting. Prof. Sargent plants the seeds in 
the beginning of winter ina moderately warm green-house, and Mr. 
Fuller recommends planting in the spring in a bed, “ the soil of which 
should be at least half leaf mold or peat from a swamp, the remainder, 
any good garden soil. Surround the bed with boards a foot or more 
in height, mix the soil thoroughly, rake level, and sow on the sand 
containing theseeds. Sift over this sufficient soil to cover the seeds about 
a quarter of an inch deep, give a good soaking of water and place a screen 
over the frame. It may be made of lath, coarse cloth, or any thing 
that will partially shade the plants when they come up, but not wholly 
exclude the light.” We would add thata thin covering of fine swamp 
moss will aid in securing an even moisturein the bed. We think this 
subject worthy the attention of the amateur, and would suggest that 
those who live convenient to the habitat of the huckleberry not only 
make the experiment of growing the plants from seeds, but also try 
cultivating and fertilizing them in their native ground. 
INSECTICIDES. 
Our experience with the cabbage caterpiller, Pieris rape, L., Striped 
cucumber beetle, Diabrotica viltati, squash borer, Ageria cucurbite, 
Harris, and pea weevil, Bruchus pisi, L., has already been noted. 
The potato beetle, Doryphora decemlineatta, Say, currant worm, Her- 
natus ventricosus, Klug, codling moth, Carpocapsa pomonella, L., 
tent caterpillar, Clisvocampa Americana, Harris, squash bug, Coreus 
tristis, De Gar, and the cabbage flea-beetle, Haltica striolata, also 
engaged our attention to some extent. 
One per cent of Paris green thoroughly mixed with land plaster, 
dusted over the foliage of the potato, proved entirely efficacious in 
destroying the larve of the potato beetle, Doryphora decemlineatta, 
Say. We have reliable testimony that a still smatler proportion of the 
poison has answered equally well. Prof. Lazenby believes that a small 
amount of Paris green is surer than a larger, as the insect instinctively 
avoids a sensible quantity. There is nodoubt that farmers have often 
greatly increased the expense and danger in using Paris green, by ap- 
plying it in unnecessarily large quantities. 
The mixture used for the potato bug also destroyed the currant 
worm, Hematus ventricosus. Slacked lime was efficacious when 
dusted directly upon the insect, but not otherwise. Nothing, how- 
ever, was tried that seemed to possess any advantage over powdered 
White Hellebore for preventing the ravages of this insect. 
June 29, the foliage of twenty apple-trees, chiefly of the Rhode 
Island Greening variety, was syringed with water containing Paris 
green at the rate of a heaped tablespoonful to a barrel, as an experi- 
ment in destroying the Codling moth, Carpocapsa pomonella, L. 
The apples which grew on these trees were the fairest of the kind 
in the orchard, but were not entirely free from ‘‘ wormy” specimens. 
The small apple crop of the past season makes the ravages of this 
insect more noticeable than usual, and comparatively few fair speci- 
mens of fruit were found in the Station orchard. 
The above application had no visible effect in destroying the myriads 
of plant-lice (aphides) with which the leaves were infested at the time. 
The Tent caterpillar, |Clisiocampa] Americana, was easily and
