212 Propagation of Greenhouse Exotics. 



during bright sunshine, by means of mats. Due care mnst 

 be taken to supply them with water when required, but not 

 till it is really needful. 



When the rudiments of the second leaf are formed, the pots 

 should be removed to a shaded part of the stove, there to 

 remain till the second leaf is perfectly formed, and the rudi- 

 ment of the third leaf is visible, when they must be carefully 

 potted oif into thumb pots, in compost according to their na- 

 ture, and again put in a shaded place till- they have taken 

 root; when they should be finally but gradually exposed to 

 their respective departments, — the greenhouse sorts to the 

 greenhouse, and the stove kinds to the stove ; — and, in con- 

 clusion, I beg to say, that the sooner seedlings are potted 

 oif the better, as they do not miss their moving so much when 

 potted young. 



The young gardener must bear in mind, that the grand 

 feature to be attended to, in propagation by seed, is, that 

 it must fully reach maturity previous to gathering, for on this 

 depends its vigorous and healthy germination. The second 

 condition necessary to successful germination, is heat, and 

 this must be supplied by artificial means. The third condi- 

 tion necessary to insure success, is moisture ; therefore water 

 or some equivalent is indispensable ; but the quantity given is 

 a matter of importance, as there may be too much or too 

 little. In the first case, the seeds will burst and rot, and, in 

 the second, they will remain inactive in the soil. The fourth 

 condition necessary is air, and this must be regulated by the 

 state of the weather, still bearing in mind, that shading is 

 necessary in bright sunshine. 



I think I have extended these remarks to the full legitimate 

 length of one article, and, if considered worthy of a place in 

 your valuable Magazine, they are much at your service, and 

 I shall continue the subject in a future number.

Mr. Kennedy may be assured his article is most opportune 

 and valuable. Indeed, we view such articles as this, and that 

 upon the heath, in our last number, by Mr. Cadness, as the 

 very essence of practical knowledge. Could all gardeners, 

 who are able to impart information, but have the same liberal
