in this manner, assigning each one to its proper order; and, if he preserves his specimens for future observation, the names of the orders should always be attached, and the plants arranged accordingly.

      Again, should the reader meet with a common flower the name of which was previously known, while he is as yet ignorant as to the order to which it belongs; or, should he find a flower that he can at once identify by means of one of our illustrations; he should not rest satisfied on seeing that the name of the order is given beside the name of the plant, but turn to the synopsis, and note the distinguishing characters which determine the natural position of the plant. In this way he will cultivate the habit of careful observation; will make much more rapid progress in forming an acquaintance with plants in general, and will soon become familiar with those natural affinities which mark, more or less distinctly, a cousinship among the flowers.

      To aid the reader in this part of his work we have given the name of the natural order with the name of every plant described; and, where difficulties are likely to occur in the identification of similar common species of the same genus, though perhaps only one member of the genus has been selected for description, a few notes are often included with the object of assisting in the identification of the others.

      In our descriptions of wild flowers we do not always repeat those features which are common to the species of their respective orders. These features are, however, of the greatest importance; and thus it is essential that the reader makes himself acquainted with them, by referring to the synopsis of the orders, before noting those characters which are given as being more directly concerned in the determination of the species themselves. Thus, when we describe the Pasque Flower (p. 297) we do not refer to those general characters that apply to all the Ranunculaceæ or Buttercup family, and which may be seen at once by referring to p. 17, but give all those details that are necessary to enable one to distinguish between the Pasque Flower and the other members of the same order.
