There are but few persons who will disallow the utility of an invention, whose object is to prevent, as much as possible, the frequent and terrible accidents which occur from the present mode of attaching horses to carriages, and other vehicles; that these might in a great measure be avoided, by the application of the Marquis's invention, and a legislative enactment to secure its adoption, there can be no doubt. To accomplish this very desirable object, a bar, of equal length with the axle-tree, to which is fixed the pole and traces; must be furnished with three iron bolts made to fit a like number of sockets in the axle-tree; and from which, the additional bar may be readily raised, by the application of a common lever: either by the pressure of the driver's foot, or by a string made to communicate with the body of the vehicle. For a chaise the apparatus will be no less simple, with the exception of a small resting bar, or foot, which it will be necessary to discharge by the same lever which sets at liberty the horse, and by this means prevent the sudden jerk, that must otherwise occur in a two wheeled carriage. No. XX. How to bring up water balance-wise, so that as little weight or force as will turn a balance, will be only needful, more than the weight of the water within the buckets, which counterpoise and empty themselves one into the other, the uppermost yielding its water (how great a quantity soever it holds) at the same time when the lowermost taketh it in, though it be an hundred fathom high. NOTE. An engine answering the above description may be composed of a series of ladles or buckets, the handles of which being hollow will admit a passage for the water by elevating the bucket end. A number of these, sufficient for the required height, must be fastened in a frame; each ladle being suspended by a fulcrum so balanced that when filled with water, they may remain in equilibrio. The whole of the buckets thus constructed may be connected by rods passing from the top of the machine to the lowest handle, and the continued series so placed, that the handle of the one bucket will empty itself into the reservoir of the succeeding one, so that by alternately raising and depressing the rods the water is raised to the top of the machine. No. XXI. How to raise water constantly with two buckets only, day and night, without any other force than its own motion, using not so much as any force, wheel, or sucker, nor more pullies than one, on which the cord or chain rolleth, with a bucket at each end. This, I confess, I have seen and learned of the great mathematician Clavius's _Studies at Rome_, he having made a present thereof unto a cardinal; and I desire not to own any other man's inventions; but if I set down any, to nominate likewise the inventor.
