How many would willingly take up afresh the recreation of their boyhood, and, under more genial skies and in more prolific hunting-grounds, pick up the broken links of old associations, and add a new source of enjoyment to their wanderings by the help of a handbook of this size and scope!

For such as these, therefore, the present work has also been prepared; and the tourist will find that, by enveloping his captures in the manner hereafter described, he will be able to bring home a really fine collection, with but short expenditure of time and trouble, and a scarcely appreciable addition to his baggage.

It is a source of surprise to those who have collected abroad that so few add this delightful pursuit to the pleasures of their holiday on the Continent.

How much can be done in the course of a month, a week—nay, even a day, will scarcely be believed except by those who have had experience.
