"It is not good for canaries till the spring," I replied. Then I went to the end of the shed to see if there was plenty of fat bacon hanging up--the birds' cod liver oil, as old Nana calls it. I inspected a piece some three inches long and two wide. It was pecked all over by voracious little beaks, and was quite thin in places. Fat bacon is an excellent adjunct to an aviary, and is one of the best means of keeping birds in health, and of special value to hens during the nesting season. In winter, also, it seems to be very nourishing, and to give great gloss and lustre to their plumage. After seeing that their larder was well supplied, I turned to their baking-tin, full of red sand and very fine oyster grit. It is really astonishing, what an amount of grit all birds require to keep them in health. I poked up the contents of the tin with my walking-stick. It was amusing to watch the birds. In a moment all had left the seed, egg, or potato, and were engaged in picking up the freshly turned sand. A few months ago I was obliged to have the floor of the aviary firmly cemented down, as otherwise I found that mice burrowed from underneath and effected an entrance, and then attacked my pets. The cement in a few days hardened, and now is like a rock, and I am glad to say inroads from the furry little barbarians have become impossible. "My children of light," as I call them, having been visited, I turned away and escaped with Bess out of the aviary, but not without great care, and having resource to some stratagems, for my little feathered friends all followed me closely, curious, and always hoping for fresh delights. At a given signal, Bess slipped under my arm, and we closed the door like lightning behind us. As we mounted the stairs, we saw the old gardener Burbidge waiting for us at the top. He looked like a picture of Old Time, with his grey hair, his worn brown overcoat, his long grey beard, and behind all, the background of snow. "They are all well," I called out to him, "in spite of the cold." "They was matted up yesterday," answered the old man, pointing downwards to my pets. Then he went on to say how he and the gardeners strengthened the artificial hedge on the east side, by adding fir branches and some mats, "for it was fit to blow their feathers out, that mortal sharp was the eastwinder;" and Burbidge looked at my pets with indulgent pity, and added, "They be nesh folks, be canaries, for all they write about them." Then he suspected Bess of giving them forbidden food. "They mustn't have no green food. It be as bad for 'em as spring showers be for sucking gulleys" (goslings), he added, "and that be certain death." "But I haven't given them anything not allowed," stammered out Bess, indignantly; "mama and I have only given them what we always do." "Ah!" said Burbidge, softening, "that won't be no hurt then; and as to potato and apple, they be the best quill revivers out, come winter. But what sort of apple was it?"
