GLASS STRUCTUEES AND APPLIANCES.

tannia Works, Wharf Road, City Road, London, give 

 the following- instructions for glazing-, and as they 

 are concise and to the point, it may he well to rej^eat 

 them : — " The lead strips arc to be fastened down the 

 centre of the rafter, previously well painted, leaving 

 the grooves clear. This should he done with three- 

 quarter-inch copper tacks, eight-inch pitch, i.e., four 

 inches apart on the alternate sides of the upright 

 flange. On lights, doors, and all movable parts, the 

 tacks should be half these distances apart. The base 



which are given in detail, the reader will gather that 

 the Simplex system of glazing can be adapted to any 

 kind of glass structures, and that any ordinary 

 estate carpenter can erect and complete a house, or 

 convert an existing house, and a gardener can re- 

 j)lace all glass broken by accident. The cost, in the 

 first instance, is slightly in advance of the best putty 

 glazing, but this is very soon rei^aid by subsequent 

 economy in maintenance and repairs, irrespective of 

 the comfort derived from the work being always in

of the lead-work should then he dressed perfectly 

 fiat on the wood, with the grooved edge of a wooden 

 tool called the 'boat' hammered along its top. 

 Not less than 21 oz. glass should be used, and 

 must be cut full, so as to allow just enough room to 

 drop in between the flanges without forcing. Before 

 2^1acing the glass in position, the angles which are to 

 receive it must be well coated with best white lead 

 paint, mixed very thick and applied with a small 

 brush. Squares of glass which are not quite flat 

 should be laid (contrary to the u&ual practice) with 

 their hollow sides downwards ; but those which will 

 Tiot bend without force should be rejected. Place 

 the glass into position with the smallest possible lap, 

 three-sixteenths of an inch, turn down the lead 

 flanges with the 'boat,' which should be slightly 

 greased, and dress down the lead so as to follow the 

 surface and close up against the biitt end of the 

 glass. Wipe off the paint squeezed out, and the 

 trvork is finished."

liendles Indestructible System. — The patent Inde- 

 structible system brought out by Messrs. Rendle and 

 Co. has long been before the public, and is exten- 

 sively patronised by the Government, the nobility, 

 numerous public bodies, and many of the winter 

 garden companies throughout the kingdom. So 

 complete is this system of glazing without putty, 

 while all the penshable materials such as wood, iron, 

 or paint are carefull}^ covered by the glass, that the 

 name given to the system may be said to be fairly 

 merited. Another great recommendation is the fact 

 that there is no breakage from expansion or con- 

 traction, either from heat or cold, as the glass has 

 full play in every direction ; moreover, the everlast- 

 ing expense of repainting, reputtying, or reglazing 

 is completely done away with. 



The chief peculiarity of this mode of constructing 

 and glazing hot-houses is the simple way in which 

 the squares of glass are fixed and kept in position by
