==Sowing and Transplanting.==—­The 1st of March is early enough for a first sowing anywhere of a small variety, and this will require a mild hot-bed, or a place in the propagating house.  Sow on rich fine soil in boxes, cover lightly, and place in a temperature of 60 deg..  When forward enough prick out the plants on a rich bed close to the glass, in a temperature of 60 deg. to 65 deg., keep liberally moist, and give air, at first with great caution, but increasing as the natural temperature rises until the lights can be removed during the day.  The plant may thus be hardened for a first planting on a warm border in a bed consisting of one-half rotten hot-bed manure and one-half of turfy loam.  The bed need not be deep, but it must be constantly moist, and old lights should be at hand to give shelter when needful.  If well grown in trenches, this first crop will be of excellent quality, and will come in early.

For the general crop a second sowing may be made of the finest Red and White varieties, also on a mild hot-bed, in the second week of March, and have treatment similar to the first, but once pricking out into the open bed will be sufficient, the largest plants being put out first at six inches, and to have shelter if needful; other plantings in the same way to follow until the seed-bed is cleared.  By good management this sowing may be made to serve the purpose of three sowings, the chief point being to prick out the most forward plants on another mild bed as soon as they are large enough to be lifted, and to make a succession from the same seed-bed as the plants advance to a suitable size.

The third and last sowing may be made in the second week of April, in an open border, on rich light soil, and should have the shelter of mats or old lights during cold weather.  From this, also, there should be two or three prickings out, the first to be transferred to a bit of hard ground, covered with about three inches of rich mulchy stuff, in the warmest spot that can be found, and the last to a similar bed on the coldest spot in the garden.  In the final planting the same order should be followed.  The result will be a prolonged supply from one sowing, and the first lot will come in early, though sown late, if the plants are kept growing without a check, and receive thoroughly generous culture.

==The planting out== is an important matter, and each lot will require separate treatment, subordinate to one general and very simple plan.  Celery must have rich soil, abundant moisture, and must be blanched to make it fit for table.  There are various ways of accomplishing these ends, although they differ but slightly, and common sense will guide us in the matter.  For the earliest crops the ground must be laid out in trenches, with as much rich stable manure dug in as can be afforded.  To overdo it in this respect seems impossible, for Celery, like Cauliflower, will grow freely in rotten manure alone, without any admixture of loam.  The trenches should
