If they fell to the ground they would be liable to be eaten by mice, etc. On the branches, however, they are sufficiently protected by the thorns and prickles. If we examine a leaf-bud, say in December (Figs. 125-130), we shall find that it consists of a number of scales with three more or less well-marked projections at the apex. In this case the scale itself represents the leaf-base, while the stipules and upper part of the leaf are indicated by the three points. The outermost scale is the shortest, and they gradually increase in length. After about ten of such scales the little leaf- blade becomes much larger, and the leaf-base smaller in „ ,„, ^ ^. ^ ^ , „ _, ,.
