Quotation from: The Call of the Wild

Written by: Jack London

The drivers confidently expected a long stopover. Themselves,
they had covered twelve hundred miles with two days' rest, and in
the nature of reason and common justice they deserved an interval
of loafing. But so many were the men who had rushed into the
Klondike, and so many were the sweethearts, wives, and kin that
had not rushed in, that the congested mail was taking on Alpine
proportions; also, there were official orders. Fresh batches of
Hudson Bay dogs were to take the places of those worthless for the
trail. The worthless ones were to be got rid of, and, since dogs
count for little against dollars, they were to be sold.
