Greenhouse construction and heating: containing full descriptions of the various kinds of greenhouses, stove houses, forcing houses, pits and frames, with directions for their construction, and also descriptions of the different types of boilers, pipes, and heating apparatus generally, with instructions for fixing the same. Greenhouses. PIT AND FEAMES. 123 from strong sun only, with no shade whatever at other times, and in order to secure these conditions, and obtain the best results, a moveable blind of some kind becomes an absolute necessity. In private gardens of any pretentions, as well as in some of the better class of nurseries, most, if not all, of the plant-houses are consequently now fitted with blinds of some kind, and the question now arises, " which is really the best of the several methods of fixing them " ? A blind fixed so as to be easily rolled up and down at will is easily fitted. to a small structure of not more than 15ft. or 20ft. in length, but when a perhaps lofty roof of 50ft. or 100ft. in length has to be dealt with the task becomes much more difficult. There are two chief methods by which greenhouse blinds (which are always placed outside, of course) may be fixed :—(1) with a. fixed roller at the top (apex of the roof) after the manner of an ordinary window blind, as at A in Pig. 79, and (2) with the blind fixed at the top and a moveable roller fastened to its lower edge,.
