The flowers are divided first, according to colour, then, according to natural classification. Since flowers are exceedingly variable in colour, and in no case constant, it is difficult to arrive at their true colour value; and, besides, most persons have their own ideas regarding colours. Purple, for instance, ranges from lightest to darkest blue, but is more or less generally understood to be a reddish blue, and it is largely a matter of qualifying its shade. Therefore, the simple primary colours have been selected as a basis, and the flowers have been arbitrarily divided into Red, Pink, Yellow and Orange, Greenish and White, and Blue and Purple groups. The student is thus enabled to turn immediately to the group of any particular flower he may desire, according to its dominating colour, without searching through an indefinite mass of descriptive matter. A small magnifying glass will reveal wonders as remarkable as those of fairyland. Such a glass, together with a few needles and a sharp penknife for dissecting the specimens, makes a satisfactory outfit for general study. A small note — book for records and a tin collecting box are also strongly recommended.
