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 repeat 

 them :— '• The lead strips ai-e to he 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, U., tow 

 inches apart on the alternate sides of the upright 

 flange. On lights, dooi-s, and aU movahle parts, the 

 tacks should he half these distances apart. The base 



which are given in detaU, the reader will gather that 

 the Simplex system of glazing can he 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- 

 place all glass hroken by accident. The cost, in the 

 first instance, is slightly in advance of the hest putty 

 glazing, but this is very soon repaid by subsequent 

 economy in maintenance and repairs, irrespective of 

 the comfort derived from the -n-oik being always in

of the lead-work should then be dressed perfectly 

 flat 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 out full, so as to allow just enough room to 

 drop in between the flanges without forcing. Before 

 placing 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 usual practice) with 

 their hollow sides downwards ; but those which will 

 not 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 butt end of the 

 glass. Wipe ofE the paint squeezed out, and the 

 srork is finished." 

 From the foregoing remarks and instructions.

SendJe's 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 Grovemment, 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 perishable materials such as wood, iron, 

 or paint are carefully 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
