HOW TO ARRANGE THE SHELLS IN THE CABINET.

When you have arranged your specimens in the order above indicated,

proceed to place them in your boxes, arranging and labelling them after

the manner shown in the accompanying diagram.

On the lid, or on a slip of paper or card placed at the head of your

columns of trays, write the class and order, with its proper number

(I., II., etc., as the case may be); then at the top of your left-hand

column place the family and its number, and under it the name of the

first genus. The species (one in each tray) come next, then the name

of the next genus following it, succeeded by its species, and so on.

The object of the young collector should be to obtain examples of as

many _genera_ as possible, since a collection in which a great number

of genera are represented is far more useful and instructive than one

composed of a great many species referable to but few genera. He will

also find it very convenient to separate the British Shells from his

general collection, sub-dividing them for convenience into "Land and

Fresh-water," and "Marine." Of these he should endeavour to get every

species, and even variety, making the thing as complete as possible.

Or a separate collection may be made of all those kinds which he can

find within a certain distance of his own home. A collection of this

sort possesses, in addition to its scientific worth, an interest of

its own, owing to the local associations that invariably connect

themselves with it.
