The more heat, the more moisture may be allowed, and, vice versa, the less heat, the less moisture. Hence, if the heat of the dung-bed declines, or if there come cold weather, at once reduce the supplies of moisture. On the other hand, give water freely if the heat is steady and the cuttings are beginning to grow, which is invariably a sign that they have roots.

Pot them off as soon as possible after they have formed roots. In potting, be careful not to break the newly-formed roots. No matter what the plants are, the soil at the first potting should be fine, and with a considerable proportion of silver sand added. Generally peat and leaf-mold answer admirably as a staple for potting newly-struck cuttings.

Pot in small pots; there is nothing gained by putting the young plants in large pots at first; the soil gets sour before they can root into it. When a few cuttings are struck in common pots, place them next the side of the pot all round.

If the heat can be regulated at will (as in propagating by means of hot water), begin at 60°; after three or four days, increase the heat 5°, in three or four days another 5°, and so on, never passing 75° or 80°, and better to stop at 70°. Too quick a growth results in weakness to the plant.

' Cuttings damping off may often be saved by sprinkling silver sand or peat-dust previously dried in an oven, over the surface of the pans. If mildew appear, give air, and dust the leaves with sulphur. Whenever damp breaks out, increase the heat and give more air.

Do not keep cuttings shut up close any longer than can be helped. Give air as soon as they are able to bear it; of course, very little at first, and with great care not to chill them.

After potting, place the pots in bottom-heat, if possible, to promote the formation of fresh roots. Never shift till the first pots are full of roots; then shift without delay, and use the compost proper to the plant. - Floral World.
