Note 43 — PETER KALM’s TRAVELS. (continued 2)

Bullfrogs43 are a large species of frogs, which I had an opportunity of hearing and seeing to-day. As I was riding out, I heard a roaring before me; and I thought it was a bull in the bushes, on the other side of the dyke, though the sound was rather more hoarse than that of a bull. I was however afraid, that a bad goring bull might be near me, though I did not see him; and I continued to think so till some hours after, when I talked with some Swedes about the Bullfrogs, and, by their account, I immediately found that I had heard their voice; for the Swedes told me, that there were numbers of them in the dyke. I afterwards hunted for them. Of all the frogs in this country, this is doubtless the greatest. I am told, that towards autumn, as soon as the air begins to grow a little cool, they hide themselves under the mud, which lies at the bottom of ponds and stagnant waters, and ly there torpid during winter. As soon as the weather grows mild, towards summer, they begin to get out of their holes, and croak. If the spring, that is, if the mild weather, begins early, they appear about the end of March, old stile; but if it happens late, they tarry under water till late in April. Their places of abode are ponds, and bogs with stagnant water; they are never in any flowing water. When many of them croak together, they make an enormous noise. Their croak exactly resembles the roaring of an ox or bull, which is somewhat hoarse. They croak so loud, that two people talking by the side of a pond cannot understand each other. They croak all together; then stop a little, and begin again. It seems as if they had a captain among them: for when he begins to croak, all the others follow; and when he stops, the others are all silent. When this captain gives the signal for stopping, you hear a note like poop coming from him. In day-time they seldom make any great noise, unless the sky is covered. But the night is their croaking time; and, when all is calm, you may hear them, though you are near a mile and a half off. When they croak, they commonly are near the surface of the water, under the bushes, and have their heads out of the water. Therefore, by going slowly, one may get close up to them before they go away. As soon as they are quite under water, they think themselves safe, though the water be very shallow.
