Dr. Darwin has collected many of these signs in the following verses.
The hollow winds begin to blow;
The clouds look black, the glass is low;
The soot falls down, the spaniels sleep;
And spiders from their cobwebs peep.
Last night the sun went pale to bed;
The moon in halos hid her head.
The boding shepherd heaves a sigh,
For, see, a rainbow spans the sky.
The walls are damp, the ditches smell,
