sight. The rain-water from the roof is collected into 

 a tank which is placed inside the aviary, and this 

 supplies the fountains. Half of the top of the flight 

 is covered with Duroline, the same material as was 

 used on the roof of the Royal Aquarium. Each flight 

 is 15ft. by 12ft. Dividing the flights from the houses 

 is a wall about four feet high with six feet of glass 

 above it, making the total height loft. There are two 

 windows, which can be opened or closed as desired, in 

 each compartment. Strawson's patent glazing is used, 

 no putty being needed, and any of the panes can be 

 replaced in a very short time; in fact, if necessary, 

 €.g. in the summer time, the whole of the glass can be 

 removed, thus leaving the aviary open in front. The 

 doors are half glass and half wood ; all the glass is 

 protected with wire netting on one side. Firs and 

 other branches are hung up, the doves and other birds 

 taking full advantage of them. The seed is supplied 

 in trays. Each house is 12ft. by lift., divided by 

 wirework, (light straight- wired bird lattice), whilst at 

 the back, the whole way along, dividing the houses 

 from the passage, the same wirework is used. All the 

 doors are opposite one another, and no wooden or 

 brick partitions are used. The birds can therefore see 

 anyone who enters the aviary, and are not frightened 

 as they would be if opaque partitions had been used. 

 A small green-house is first entered before the six- 

 feet passage can be reached, this being divided from 

 the aviary by a door which prevents any stray bird 

 escaping. A 2ft. 6in. shelf runs along the length of 

 the brick wall at the back for the caged birds, and 

 underneath are kept the various bins for storing the 

 seed, etc. At the far end of the aviary is the rain
