338 Transactions of the Prussian Gardening Society. 



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

 Roskelt's, at Gatacre, near Liverpool; and at Bargany and 

 Castle Semple, for pine-apples ; and we were perfectly satisfied 

 of its efficiency. The pine-apples which were planted out in 

 the soil at Castle Semple did not appear to show fruit so soon 

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

 to do with the mode of heating.

 of the Society for the Advancement of Gardening in the Royal 

 Prussian States. 4to. Vol. III. Berlin, 1827- 



The present volume contains a number of translations from 

 the London Horticultural Society's Transactions, 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. Schram. 

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

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

 forcing-houses. The 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 matured on trees that have not been transplanted the 

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

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

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

 being forced are 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 form, with boarded 

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

 places, and sheet-iron flues. 



3. On Hibiscus fugax 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 kept rather dry. It grows well in leaf mould and sand, 

 and is easily propagated by cuttings and layers of its angular 

 stems.
