As regards the habits of the Canary when tamed, we quote Lenz, a naturalist well qualified to furnish all the particulars that could possibly be desired:--"In order to ascertain where the finest specimens could be obtained, I sought throughout the whole of Germany and its surrounding countries, not omitting to place myself in correspondence with various distant portions of the world, and am now fully persuaded that the choicest birds are to be procured at Andreasdorf, in the Hartz Mountains, and the neighbouring villages. In the above-mentioned place almost every house has its breeding-room set apart for their cultivation. Many families live entirely by this means, and we were told by an official belonging to the place that Canaries are sold to the value of 12,000 rix-dollars during the course of the year from this village alone. It is quite unknown when this business was first established in the Hartz Mountains, but that locality affords in plenty three great requisites for its success: wood in such profusion that the cost of warming the Canaries' apartments throughout the year is very trifling, abundance of rapeseed, and white bread, the corn for which is grown with ease in the beautiful meadows that surround the villages. The songs of the birds reared on this spot are very various, but in no case have we heard a really bad singer, while many possess voices of unusual power and sweetness." In Andreasdorf a bird of uniform pale yellow plumage, and without a crest, is much preferred, because those that are uniformly tinted cannot be spoilt by irregular markings, and because the male nestling of this species is easily recognised on account of its tints about the eyes and region of the beak; even after the young have left the nest this distinguishing feature is for some time observable, and the sexes may be thus readily ascertained. The superfluous female birds are sent early in the summer upon their travels through the world in the care of an itinerant salesman, and hundreds of the males are taken in October and November to be sold by wholesale dealers in large cities, or exported to Russia and America. The Canaries reared in other neighbouring districts cannot equal those of Andreasdorf in their song, though they are very superior to such as are obtained elsewhere. The following hints may perhaps be useful to our readers in the choice of a tame specimen:--First, entirely green birds, or such as are brightly marked with green, are usually very strong, and, in consequence, their voice is often disagreeably loud; secondly, such as are of a yellowish brown or dark yellow are weakly, and seldom breed; thirdly, the variegated kinds do not often have prettily-marked young; fourthly, such as have red eyes are weak; and, fifthly, should birds with a crest be preferred, the purchaser must be careful that there are no bare spots on it. In order to ensure a good singing Canary, it is necessary to procure
