At times there were dozens of these guns and rifles to be seen on the wall at Uncle Jim's hotel.

The visible supply fluctuated somewhat.
Any observer of industrial economics might have discovered it to move up or down in unison with the current amount visible of the circulating medium.
Uncle Jim never asked cash or security of any man.

If a man paid, very well.

If he did not pay, it would have been unkind to ask him, for assuredly he would have paid if he could, as Uncle Jim very well knew.

And if he could not pay, none the less he needed to eat, as Uncle Jim also knew very well.
