Pedro Velasquez, Memoir of an Eventful Expedition in Central America
“ The fugitives had scarcely reached the secluded retreat of Vaalpeor, and mounted their mules, before the low yelp of blood-hounds was heard upon their trail and soon burst into full cry. But the dogs were somewhat confused by the scent of so many footsteps on the spot at which the party mounted, and did not follow the mules until the horsemen led the way. This afforded time for the fugitives, racing their swift mules at full speed, to reach the opening of the valley, when Velasquez wheeled and halted, for the pursuers were close at hand. ”
