merely for a flat top, which lies level inside along the bottom of its box, as shown in Plate III., where the cage is represented as utterly in its separated parts. With waggon cages accordingly, you would be obliged to place. portions 1 and 2 reversed in position to those they occupy in that diagram; and another thing would be, that in place of its receiving table being light, elegant looking, and square, as in Plate II., with the cage upon it, the general effect would be bad and unpleasing as an article of furniture. For consideration of Dick's own sentiment as to shape of his roof, he has usually shown himself most complacently indifferent, provided only the rest of the necessary details of his house be particularly attended to; so in that matter you will have merely your own personal taste to consult. Some birds have the dangerous habit of twirling, that is, craning upwards till they topple over the perch and break their necks. Java Sparrows and most of the foreign species do this, and in their behalf you will find it essential to provide aviaries with perforated zinc tops, if rounded cages like the waggon; if flat, I would recommend, in preference, a simple plate of enamelled zinc instead, either as attached, or laid on when needful; because all the feathered tribes do not alike "twirl," and where these do not, the cage looks infinitely prettier transparent, and also more in keeping with the plainly wired walls and partitions. I have given diagrams solely of the square cage, as this, in my judgment, is the most. convenient to use, and better illustrative of the design of taking quite to pieces when desired, for cleaning or other

wise. The waggon can as easily be made to order on the same principle.

The model cage consists of thirteen essential parts, exclusive of the perches. These fit with mathematical precision into each other, and divide again with similar exactitude to pack into their box, with its four legs laid beside the cage itself lightly and precisely beneath the lid, as in Plate III.; so that whenever required, the case containing its treasure has merely to be unlocked and emptied of its contents; the legs screwed on, the lid put down once more, and the metal structure pieced accurately as easily into the form it presents in Plate II., which shows our model cage first as it would be seen in statu quo in its own chosen window, and secondly, where it lies simply corded with the rest of your luggage upon the railway platform, the upper portion being the usual food and water vessels placed, joined together visa-vis, as in Plate III.; the left hand drawing, number 12, where extra perches are supposed to be, and the birds too moreover, carefully covered all over by their redbraid-bound holland travelling cover, tied neatly with bow and end at each corner, with its one broad hole on top to admit the air, as in Plate II., figure 4. Or else, the birds not being thus carried about, the breeding boxes number 16, holding the superflous china vessels for the soft food, or whatever else you may need these for, should be laid within one another, as in figure 16, illustrated by the dotted lines showing how and where they would meet when face to face, and then placed inside bodily within

the diagram 12, and closed up and covered over, will look as it does in Plate II., number 4. In moving birds, however, you should never give them out of your own hand, as they become much less frightened and agitated when with their habitual and familiarly accustomed keeper, than if entrusted to strangers, whose voice, manners, and touch they do not know; and of course, it is a fact that undue excitement of any sort is always prejudicial to a poor little helpless bird, and the more delicate and valuable these be, the worse for them, quite as much as for their owner, as impaired health spoils beauty in all things, and depreciates value.

The thirteen essential parts of our model cage are as follows. 1. The roof, of which we have already treated, and need not refer to again. 2. The two "long walls," as for the sake of distinction I will call them, namely figures 9 and 10 in Plate III.; each of these being furnished with its own permanently attached door, 18 and 19, wired liked itself, and in opposite sides when put up, as shown in the various Plates. Of these permanent doors, one opens near the roof 18, the other from the tray 19, and being for your convenience in cleaning, &c., and not Dick's, should be wired "transparently," as they are thus less obtrusively visible, and answer your purpose just as well as if made upon the contrary principle of the crossed, small, provisional doors, numbers 6 and 7, in Plate III. 3. The two short walls," of which I give for the sake of space, merely one instance in Plate III., namely figure 5. These should
