THE FLORAL WORLD AND GARDEN GUIDE. 



In pruning glabra the wood of the previous season should be cut 

 back to two eyes, and the young shoots thinned out to one to each 

 spur. This operation should be performed when the plants are 

 quite at rest, which, as a rule, occurs early in January. This is also 

 the best time to repot, as the cultivator has more spare time, gene- 

 rally speaking, at that season thau, perhaps, at any other ; therefore 

 everything that refers to pruning and training should be done when 

 the time can be afforded for doing it properly. The trellis to my 

 mind most suitable for training the Bougainvillea is one either in 

 the shape of a barrel or balloon. Both these display the lovely 

 colour of the flowers to great advantage, as well as to permit of the 

 growth being trained more easily. The compost I have found best 

 suited to their requirements is prepared by well incorporating toge- 

 ther two parts good turfy loam, and one part each of fibry peat and 

 leaf-mould, with a proportionate quantity of silver-sand. A few 

 nodules of charcoal may also be added to this compost. 



The pots into which the plants are intended to be put should be 

 perfectly clean and well drained. A few pieces of charcoal may also 

 be advantageously mixed with the drainage.

SENDEE'S PORTABLE PLANT PEOTECTOES. 



T the exhibition of the Eoyal Horticultural Society, held 

 at Nottingham last July, Mr. W. E. Eendle, the 

 inventor of the " Portable Plant Protectors," figured 

 in the Floral World for January, 1S70, exhibited 

 several new and improved forms of these invaluable 

 to which we have for some time past been anxious to 

 direct attention. The principles upon 

 which these Protectors are con- 

 structed were briefly described in 

 the communication referred to, and 

 beyond saying that they have, in 

 their usefulness for protective pur- 

 poses, more than justified all that we 

 said in their praise when introducing 

 them to the notice of our readers, we 

 need not further allude to the old 

 form. The old forms are retained, 

 but very material improvements have 

 been effected in the details of con- 

 struction, and by the introduction of a 

 movable coping as here shown (Fig. 1), 

 increased facilities are provided for the removal of the glass, and 

 the invention is now as perfect as it possibly can be. The span roof 

 protectors now come almost within the category of houses, for they 

 can be had of any width, ranging from three to eight feet wide. 

 Fig. 2 represents one of the last-mentioned width, with galvanized 

 middle grooves to hold the glass ; but those not exceeding four feet 

 in width do not require the grooves, as one sheet of glass on each
