Considering, I see too that they

Have a busy life, but plenty of play;

In the earth they dig their bills deep,

And work well, though they do not heap;

Then to play in the way they are not loth,

And their nests between are better than both.

But this is when there blow no storms,

When berries are plenty in winter, and worms,

When feathers are rife, with oil enough

To keep the cold out and send the rain off;
