The _Lobelia inflata_, Indian-tobacco, meets me at every turn. At first I suspect some new bluish flower in the grass, but stooping see the inflated pods. Tasting one such herb convinces me that there are such things as drugs which may either kill or cure.[296] The _Rhexia Virginica_ is a showy flower at present. How copious and precise the botanical language to describe the leaves, as well as the other parts of a plant! Botany is worth studying if only for the precision of its terms,—to learn the value of words and of system. It is wonderful how much pains has been taken to describe a flower’s leaf, compared for instance with the care that is taken in describing a psychological fact. Suppose as much ingenuity (perhaps it would be needless) in making a language to express the sentiments! We are armed with language adequate to describe each leaf in the field, or at least to distinguish it from each other, but not to describe a human character.

Every traveller has just as particular an errand which I might likewise chance to be privy to. Now that I am at the extremity of my walk, I see a threatening cloud blowing up from the south, which however, methinks, will not compel me to make haste. _Apios tuberosa_, or _Glycine Apios_, ground-nut. The prenanthes now takes the place of the lactucas, which are gone to seed.
