The first thing to be secured is an immunity from frosts. It does not signify their being subjected to a low temperature at night - such is, indeed, desirable - but they will not endure frost as to the blossoming principle. I am here speaking of the Neapolitan Violet, for no other will force so successfully, as far as I am aware, in frames or pits. Let me then suggest a standard of temperature; I will merely point to that proper to obtain if possible. From the early part of November to the end of February, I should desire from 40° to 55° by day, and 34° to 40° by night. But we all know that such precise conditions are not easily attainable; all I can say, then, is, approach this standard as nearly as possible, only do not let them freeze. But there is another feature attending the culture of winter violets which is of equal importance to any-other condition; it is this - the avoidance of damp. To this they are very liable, especially after being shut up for days, as in the case of snowy periods and those of intense frost And I may here remark, that the more gross the plants are, the more liable are they to a kind of putrefaction in the foliage.

This is to be particularly guarded against, for it spreads like wildfire, and, if not checked, will speedily undermine the utility of the plants. Dryness of the internal air of the frame or pit is, therefore, one of the leading features in violet culture, and must be promoted by all means in our power. This caution at once points to the reason why but one watering had been given the pit. Therefore, to plant them in a tolerably dry or mellow medium, and to sustain them afterwards with as moderate an amount of water, is one of the grand points to aim at. And let no man be alarmed at their looking dry or husky on the surface; this is just as it should be, for the violets are not merely blossoming through the soil they are in, but through a disposition which has been engendered in them during the out-door summer culture.

Let me direct attention to their ventilation; nothing requires more of this than the violet On all occasions, let even the.very lights or sashes be pulled off in the daytime, provided they neither freeze nor receive any rain, or otherwise that there be no cutting winds.
