Long, stinging cry of a locust comes in from a tree, half a mile off; had forgotten there was such a tree.

Baby's screams from a house several blocks distant;--never knew there were any babies in the neighborhood before.

Tinman pounding something that clatters dreadfully,--very distinct, but don't remember any tinman's shop near by.

Horses stamping on pavement to get off flies.

When you hear these four sounds, you may set it down as a warm day.
