The Crocus, Snowdrop, and Dog’s-tooth Violet. —The 
various sorts of Crocus, Snowdrop, and Dog’s-tooth Violet, some 
of them natives of England, are not very difficult to cultivate; 
but they are particularly pleasing in their effect, as they bloom 
in company with each other. 
The corms of the Crocus must be planted to the depth of 
two or three inches, either in beds by themselves, about four 
inches asunder, or patches of five or six in each. They look 
extremely well to form margins to clumps and borders, placing 
them in a varied manner with respect to the sorts. Great 
injury is frequently done to the corms by trimming off the 
green leaves, for the sake of neatness, as soon as they have 
done blooming. That practice is quite erroneous, as the green 
leaves tend to nourish and strengthen the corms, and if taken off 
the future blooms will be materially injured. 
The Crocus corms should be left in the ground for three or 
four years undisturbed, with the exception of forking in a little 
fresh compost every year, as they will not bear to be kept out 
of the ground, the same as tulips and other bulbs. If the 
corms are left out of the ground to push, they will often perish, 
or, at best, flower weakly. They should be taken up as soon as 
the leaves decay, separating the large ones from the small, and 
plant them again as soon as the places are prepared for their 
reception. Any light fresh soil will do for the crocus, with a 
little well-rotten dung. 
The same treatment will be applicable for the Snowdrop 
(Galanthus nivalis) and' Dog’s-tooth Violet (Erythronium 
Dens Canis). 
ON THE APPLICATION OF CHARCOAL IN THE 
CULTIVATION OF PLANTS. 
By Mr. T. Moore. 
In estimating the uses and application of Charcoal in horti¬ 
cultural matters, we must look to the influence it exerts in two 
distinct of points of view ; viz., chemically and mechanically. In 
the first of these, that is, chemically, its action would appear to 
consist in applying food directly to the plants which are under
