bed, and in this, as in all else, there is a right and a wrong way of doing the work.  Accurately set out the space on which it is to be made.  If there is plenty of manure, make the bed large enough to project eighteen inches beyond the lights all round.  But if manure is scarce, cut the margin closer, and trust to a hot lining when the heat begins to flag.  Commence with the outside of the bed, employing the long stuff in its construction; and keep this part of the work a little in advance of the centre until the full height is reached.  A bed made in this way will not fall to pieces, and the heat will be durable in proportion to its size and thickness.  Where fallen leaves are abundant, they should be used for the middle of the bed, and they will give a more lasting heat than short manure.  When the bed has settled down to a steady temperature, add six or nine inches of mellow loam over the entire surface, upon which place the frames.  To insure drainage, it is an excellent plan to lay common flake hurdles on the top of the heap before adding the soil.  These do not in the least interfere with the free running of the roots.  It is usual to have two plants under each light, but where the management is good, one is quite enough.  The subsequent work consists of shading and sheltering, to prevent any serious check from trying weather, and in giving just water enough and no more.  The fermenting material should sustain the temperature of the frame, even during frosty nights, and mats will screen off strong sunshine as well as cold winds.  The plants will need stopping earlier than those grown in houses, and as there are no hot-pipes to dissipate the moisture, rather less water will be necessary, both in the soil and from the syringe.  But the water employed should always be of the same temperature as the bed.  This is easily managed by keeping a full can standing with the plants.  In large frames, where there is a good body of manure and the loam is mellow and turfy, pieces of Mushroom spawn can be inserted all over the bed.  The Mushrooms may appear while the bed is in full bearing; but if they do not they will come when the plants are cleared out, and pay well to keep the lights in use another month or so.

==Garlic== may still be planted, but no time is to be lost.

==Herbs== of many kinds may be sown or divided, and it will be necessary to look over the Herb quarter and see how things stand for the supplies that will be required.  A little later, excess of work may prevent due attention to this department.

==Horse-radish== to be planted, if not done already.

==Kohl Rabi==, or ==Knol Kohl==, to be sown in small quantity at the end of the month, and onwards to August, as required.  If cooked while young, the bulbs are an excellent substitute for Turnips in a hot, dry season.

==Leek==.—­Sow the main crop in very rich, well-prepared soil, and rather thickly, as the seedlings will have to be planted out.  With a little management this sowing will yield a succession of Leeks.
