They are sometimes of great magnitude; I have been assured by observers of them in factories ashore and on moored hulks that they can stand on their hind legs and drink out of a quart jug, but the most common steamer kind is smaller, as far as my own observations go. But what I do object to in them is, that they fly and feed on your hair and nails and disturb your sleep by so doing; and you mayn't smash them—they make an awful mess if you do. As for insect powder, well, I'd like to see the insect powder that would disturb the digestion of a West African insect.

But it's against the insects ashore that you have to be specially warned. During my first few weeks of Africa I took a general natural historical interest in them with enthusiasm as of natural history; it soon became a mere sporting one, though equally enthusiastic at first. Afterwards a nearly complete indifference set in, unless some wretch aroused a vengeful spirit in me by stinging or biting.
