This is the law of the Yukon, and ever she makes it plain:
"Send not your foolish and feeble; send me your strong and your sane --
Strong for the red rage of battle; sane for I harry them sore;
Send me men girt for the combat, men who are grit to the core;
Swift as the panther in triumph, fierce as the bear in defeat,
Sired of a bulldog parent, steeled in the furnace heat.
Send me the best of your breeding, lend me your chosen ones;
Them will I take to my bosom, them will I call my sons;
Them will I gild with my treasure, them will I glut with my meat;
But the others -- the misfits, the failures -- I trample under my feet.
Dissolute, damned and despairful, crippled and palsied and slain,
Ye would send me the spawn of your gutters -- Go! take back your spawn again.
--Robert Service, the first stanza of The Law of the Yukon
