Mr. Hay's mode in operation for early cucumbers, at Mr. 

 Roskell's, at Gatacre, near Liverpool ; and at Bar^any J^ihI 

 Castle Scmple, lor piue-apples ; anti we were perfectly satisfied 

 of its efficiency. Tiic j)inc-apples which were planted out in 

 the soil at Castle Semple did not appear to show fruit so soo:i 

 as those in pots; but that was to be expected, and has nothing 

 to do witli the mode of heating.

The present volume contains a number of translations from 

 the London Horticultural Society's 7)-a7isacfio?is, which we 

 shall pass over, as well as all the papers of local interest, and 

 those containing nothing but what is already' generally known 

 among British gardeners. 



1. On the Construction of Hot-houses. By M. Otto and M. Schrani. 

 Houses for keeping plants, such as green-houses, pits, 

 stoves, and conservatories, are first treated of; and, next, 

 forcing-houses. '1 ne article is of great length, very elaborate, 

 and illustrated by numerous figures. Transportable forcing- 

 houses are recommended for forcing cherries, plums, peaches, 

 apricots, &c. ; because these fruits are found better-flavoured, 

 when maturetl on trees that have not been transplanted the 

 same season, as is the general practice in Holland, Germany, 

 and Denmark. (See our account of the mode of forcing at 

 Hylands, Vol. III. p. 385.) The fruit trees designed for 

 being forced arc directed to be planted close together, that 

 they may be covered with more facility. When the trees 

 have been forced once, they are allowed at least two years of 

 rest. The houses are of the usual British Ibrm, with boarded 

 backs instead of walls of masonry, and with cast-iron fire- 

 places, and sheet-iron flues. 



3. On Hibiscus yiigax Mart. By M. Seitz. 



This is a herbaceous plant from Brazil. The stems die 

 down during the winter, when the roots, being tuberous, must 

 be kej)t rather dry. It grows well in leaf moidd and sand, 

 and is easily propagated by cuttings and layers of its angular 

 stems.
