"And the bottles and boxes that chap fetched along! Why, a doctor would never want more; If they held pills and physic, he'd got full enough To fit out a medicine-store. And he'd got heaps of pins, dreffle lengthy and slim, Allers droppin' about on the floor.
"Well, true as I live, that old feller just spent His hull days in loafin' about And pickin' up hoppers and roaches and flies-- Not to use for his bait to ketch trout, But to kill and stick pins in and squint at and all. He was crazy 's a coot, th' ain't no doubt.
"He'd see a poor miller a-flyin' along,-- The commonest, every-day kind,-- And he'd waddle on arter it, fat as he was, And foller up softly behind, Till he'd flop that-air bait-net right over its head, And I'd laugh till nigh out of my mind.
"Why, he'd lay on the ground for an hour at a stretch And scratch in the dirt like a hen; He'd scrape all the bark off the bushes and trees, And turn the stones over; and then He'd peek under logs, or he'd pry into holes. I'm glad there ain't no more sech men.

Protective mimicry as it occurs in animals may be the simulation in form or color, or both, of natural objects, or it may be the simulation of the form and color of another animal, which for some reason enjoys immunity from the attacks of species which ordinarily prey upon its kind. Of course this mimicry is unconscious and is the result of a slow process of development which has, no doubt, gone on for ages.
