198 THE GARDENER. [April 1873. 



Erratum.— In ' Gardener' for March, page 127, line 13, for " 1-iuch earth " 

 rtad ** good brick earth." 



A. B. C. — Front ventilation alone will not be suflficicnt ventilation for your 

 Peach-house. There should also be means of ventilation at the highest part of 

 the house. There is no objection to the method recommended in the work 

 you name, but we do not consider it necessary for Peaches. 



D, E. — We do not know of a work specially devoted to your subject, but it is 

 included in Loudon's ' Self-Instruction for Young Gardeners,' in which you wiU 

 find much besides that will be useful to you. 



Eeader. — We never found any difficvdty in getting a good set on the laterals, 

 and consider the sub-lateral system a mere waste of time. Your other question 

 would take up om- whole space, were we to attempt to reply to it. You will 

 see some excellent papers by our contributor "The Squire's Gardener," on the 

 subject, in our issues of 1872. 



Subscriber. — Apply to the 'North British Agriculturist,' a paper devoted 

 to farming, and published in Edinburgh. Your want is quite out of our sphere. 



T, P. — The United States is a good field for young gardeners willing and 

 able to work hard. We know of a youth who landed at Boston last fall, and 

 was engaged next day at 50s. per week as a foreman. Canada, no doubt, affords 

 good openings. 



T. G. — Boronia serrulata ; Genetyllis tulipera ; Leschenaultia formosa ; 

 Phsenocoma pi-olifera Barnesii ; Punelea Hendersonii ; Acrophyllum venosum ; 

 Eriostemum buxifolium ; Tetratheca cricoides villosa. 



Cam. — We are sorry that we cannot inform you of the publisher. Any 

 bookseller will find out for you. 



U.S. — Coniferous plants may be successfully grafted at any time between 

 the end of August and beginning of April. We prefer the end of August, or as 

 soon as the young wood is ripened. The best mode is what is known as " side 

 grafting " — that is, the top of the stock is left on till such time as the union is 

 effected. If the operation is performed in autumn, the plants should be kept 

 close and cool till early in spring, when they should have a mild heat to start 

 them into growth : if deferred till spring, they may have heat at once. During 

 the whole process a close moist atmosphere is absolutely necessary, and in all 

 cases it is of great importance to have the stocks well established in pots — if a 

 whole year, so much the better.
