As to the formation of the cabinet, and arrangement of the eggs therein, directions are scarcely necessary; this must depend very much upon the means and conveniences, as well as the taste of the collector. Shallow drawers with divisions sufficiently broad for the names of the specimens to be written or pasted along the tops, are perhaps best. Small pill-boxes, which may have the names on the lids, are not bad receptacles, and the cost of a few dozens of these is not much; but above all things let the arrangements be carried out with neatness and order; do not let the specimens be huddled together, but classified, and placed so that the hand may be laid upon any one which may be required. Duplicates for exchanging with other collectors, or replacing any which may be broken, may be put carefully in a drawer by themselves, their presence with the others will only cause unnecessary confusion and trouble. Care should be taken not to name a specimen positively, if there is any doubt of its identity, it may be named with a query; and in the note-book, which every collector should keep, should be entered all the circumstances which weigh for or against the correctness of the designation given to it. This note-book ought to be a complete record of the time and place of acquisition of every specimen included in the collection, and of all that is curious or interesting connected with it. If nests as well as eggs are preserved, of course drawers with divisions are the very best receptacles; they occupy a great deal of space, and, except in some cases where the structure is peculiarly neat or curious, it is perhaps scarcely worth while to take and preserve them, especially as doing so often involves a cruel spoliation of the feathered architects, whose carefully chosen situations for building are well described by Dr. Bidlake, in his "Walks in a Forest."
