Seven wagons were driving in a file along the road. The first six were singularly constructed. They resembled coopers’ drays; they consisted of long ladders placed on two wheels and forming barrows at their rear extremities. Each dray, or rather let us say, each ladder, was attached to four horses harnessed tandem. On these ladders strange clusters of men were being drawn. In the faint light, these men were to be divined rather than seen. Twenty-four on each vehicle, twelve on a side, back to back, facing the passersby, their legs dangling in the air⁠—this was the manner in which these men were travelling, and behind their backs they had something which clanked, and which was a chain, and on their necks something which shone, and which was an iron collar. Each man had his collar, but the chain was for all; so that if these four and twenty men had occasion to alight from the dray and walk, they were seized with a sort of inexorable unity, and were obliged to wind over the ground with the chain for a backbone, somewhat after the fashion of millipedes. In the back and front of each vehicle, two men armed with muskets stood erect, each holding one end of the chain under his foot. The iron necklets were square.
