"The accompanying engraving is an illustration of a new style vertical mill in which an attempt is made to embody all the improvements which have been suggested by experience, and to furnish a complete vertical cane mill. In this machine the hearing is placed between the rolls, giving access to the boxes; the small wheels are lapped, bringing the minor rolls close together, and dispensing with the guide plate or 'dumb returner;' the main roll has a wide flange; the sweep cap has a square eye fitted to the squared end of the main shaft removable by hand; the weight of the rolls is supported upon the ends of the shafts in adjustable oil-tight boxes; the feed roll is fluted to facilitate the entrance of the cane to the mill; the top and bottom plates are diagonally braced as represent, and the construction of the whole machine is such that the mill may be taken entirely apart by simply unscrewing the corner bolts, no keys being used in any part of the machine." -Commissioner, 1865

"To avoid the inconvenience of having the team travel around the mill, interfering with the passing to and fro with cane and bagasse, the plan has been adopted by one manufacturer at least, of prolonging the main shaft of the mill down through the floor, and there coupling it with another shaft which continues down and rests in a step on the floor of a lower story or basement. The sweep is attached to the shaft below, and the team is thus removed from around the mill leaving the space unobstructed." -Commission, 1865

A road vehicle like this one is a mechanical means of conveyance, a carriage or transport. Vehicles may be propelled or pulled by engines or animals including humans, for instance, a chariot, a stagecoach, a mule-drawn barge, an ox-cart or rickshaw. However, animals on their own, though used as a means of transport, are not called vehicles, but rather beasts of burden or draft animals. This distinction includes humans carrying another human, for example a child or a disabled person.

A tracked vehicle is a vehicle that runs on continuous tracks instead of wheels. The principal design advantages of tracked over wheeled vehicles are that they are in contact with a larger surface area than would generally be the case with a wheeled vehicle, and as a result exert a much lower force per unit area on the ground being traversed than a conventional wheeled vehicle of the same weight.

Velocipedes are an umbrella term for any human-powered land vehicle with one or more wheels. The most common type of velocipede today is the bicycle.
