A great many of our finest singers have come from Italy and France, but until we read it in an English newspaper some days ago we never knew that Germany carries on a very large trade in the rearing and exporting of canaries, and that the largest establishment in the world for the breeding of these creatures is situated within the domains of that empire, away up among the Hartz Mountains of Prussia. From this and the few surrounding but much smaller nurseries no fewer than 130,000 birds are despatched every year to the United States and Canada; while in the same time at least 3000 go to Great Britain, and about 2000 go to Russia.
