170 THE ORCHID REVIEW. [JUNE, 1909. 
ORCHIDS AT HAYWARDS HEATH. 
For several years Messrs. Charlesworth & Co. had a small establishment at 
Haywards Heath, Sussex, in addition to their Bradford establishment, and 
as it became increasingly evident that the climatic conditions of the former 
locality were much superior for Orchid culture, they decided to lay out an 
entirely new nursery there, to which the plants were all removed last 
autumn. The old nursery at Haywards Heath has also been relinquished, 
and the business is now conducted entirely from the new establishment, 
which we have just had the pleasure of seeing. 
The houses are built with all the latest improvements, and very 
conveniently arranged. A glass covered corridor of 250 feet long by 12 feet 
wide extends from the office—-which has a 45 feet frontage—back to the 
potting shed, and the last 160 feet has glass covered sides, and from this. 
portion extend, right and left, twelve houses, each too feet long, and of 
varying widths, according to the purposes for which they are intended. The 
widths are 12, 13, 20, and 213 feet, there being three of each. The packing 
shed measures 75 by 20 feet, the potting shed 80 by 20, and there is a 
photographic studio 20 feet square. There is also a block of eight seedling 
houses, each 100 feet long, extending right and left from a second corridor, 
one of these being 18 feet wide, and the rest 10 and 11 feet. The potting 
shed attached to this block measures 15 by 18 feet, and at the end of the 
potting shed are two other houses, each 25 by 18 feet. 
Ample provision has been made for a supply of rain water, large tanks 
being built across the ranges of houses, with openings under the stages of 
each, so that the supply is accessible from every point. The roofs form an 
ample collecting ground for the rainfall. Lath roller blinds running length- 
ways are fixed well above the glass roof, so as to allow an ample current of 
air beneath, but in bright weather this is found insufficient, and a layer of 
tiffany is laid on the glass itself, so as to form a double shading. As a 
temporary provision some of the glass has been whitewashed, but it is 
intended ultimately to use tiffany for this purpose. Top and side ventilation 
is provided, the latter by shutters opening outwards, worked by a handle 
from the interior, so that the proper amount of ventilation can be adjusted 
without going outside. The operator feels in a moment the current of air 
coming into the house, and can adjust the shutter accordingly, a very 
ingenious contrivance. In short, the whole arrangements have been made 
with a view to secure a constant healthy atmosphere in the houses, which is 
the chief secret of successful Orchid cultivation. But it is time to come to 
the plants themselves, and in this we must follow the order of our notes. 
_ The first house entered contained a lot of plants which may be described 
as Cool Intermediate, requiring a minimum of about 60° at night. Here we
