etc., cost me lo/- or less, I think, aud the No. 4 Bra3''s 

 burner burns 4ft. of gas per hour. Gas in my neighbour- 

 hood is 2/6 per 1, 000ft., so that the cost of heating is a 

 fraction under 3d. for 24 hours. Arthur Jones. 



Sir, — My aviary is 36ft. long by 15ft. wide, and 8ft. 

 high. It has brick walls on two sides, and on the others 

 glass and corrugated iron lined with match-boarding. 

 It is divided into six compartments, all the partitions 

 being wire above the height of 2ft. from the floor. The 

 floor is of concrete, with a trough running tlirough all 

 the compartments, with water laid on so arranged that 

 the trough can be filled or the water allowed to run 

 through it. 



Any member who is in my part of the country 

 (Southport) can have a look if he likes to call. My 

 aviary is heated with 4" hot water pipes, fed from an 

 independent boiler which requires attention twdce a-da}-. 

 I have tried both gas and oil. Gas needs less attention 

 but is expensive — I had it laid on last winter, 1)ut found 

 it cost me about 2/6 per week. I had a stove called the 

 "King of vStoves," which requires no chimney and has 

 three ordinary gas burners in it. It is very good, but there 

 is a better one made by Feulon and Son, of London, 

 which works as a radiator with gas and water— it costs 

 about ;^6. If gas is used there ought to be a ventilator 

 in the roof alwax's open. I have an Acme Ventilator in 

 the roof of my aviary, which is alwa^'s open as no 

 down draught can comedown. W. H. Foster. 



Sir, — My bird-room is heated b}- an ordinary slow 

 combustion stove. I gave 16/- for it at the A. & N. vStores. 

 I had the grate in the room stopped up, and over the 

 mantelpiece a hole cut to pass the stove-pipe through. 

 The stove stands on a large slab of stone and is inside a 

 cage of half-inch galvanized wire, high enough to enclose 

 the stove-pipe, which, I have already said, goes through 

 the wall above the chimney piece. The wire cage is 

 made on light wooden uprights, and is fitted with.
