THE FLORIST. 



VENTILATING CONTRIVANCE. 



The accompanying cut represents a method of ventilating rooms, 

 counting-houses, &c. which has been adopted for some length of 

 time, and has given general satisfaction. 



The ventilator consists of louvres, 

 or strips of glass placed horizontally 

 across the window-frame, at such an 

 angle as to cause the current of air to 

 enter in an upward direction, thus pre- 

 venting draught. It is furnished with 

 a glass slide, or shutter, by moving 

 which, the ventilation can be increased, 

 diminished, or altogether suspended at 

 pleasure. This slide can be made with 

 upward, downward, or side action, and 

 is worked by a line passing over pul- 

 leys, and brought by that means to the 

 most convenient part for handling. 



Now this is a contrivance simple 

 and efficacious, and of most easy adapt- 

 ation to the ventilation of our garden 

 glass structures. A thing so inex- 

 pensive, yet so useful, seems to address 

 itself to the commonest understanding, 

 and makes it almost unnecessary to 

 add, that its introduction at either end 

 of a greenhouse, stove, vinery, or what 

 not, places at all times in the hands of 

 the gardener a power of ventilation to 

 a greater or less extent ; but particu- 

 larly in bad weather, high winds, or in a frosty season, w r hen, after a 

 night's firing, he may wish to admit a small amount of fresh air. A 

 ventilator of this kind is fixed in each end of the Orchid-house at 

 Worton Cottage, and answers the purpose admirably. 



Mr. Dromgole, whose advertisement has frequently appeared in 

 The Florist, would be glad to answer inquiries respecting it, and to 

 furnish models to explain its working. 



ILLUSTRATED WORK ON FLORISTS' FLOWERS. 



I beg with all seriousness to call the attention of metropolitan 

 Florists to this subject ; viz. the immediate establishment of a peri- 

 odical, which shall give illustrations, or faithful portraits, of the best 

 and established florists' flowers. In this project, I do not mean to
