to do injustice; for the brigade, as a whole, has fully sustained its well-earned reputation, and given additional evidence of the disinterested devotion of Missourians to the cause of their country-showing, as heretofore, that they are always among the first in the breach, and the last to leave it. I am indebted to my Aids, Captain Edwards and Lieutenant Chesnut for the prompt and untiring energy with which they assisted me in the engagement. Major Monroe, my brigade Quartermaster, and Major Ruthven, my brigade Commissary, deserve great praise for the activity with which they discharged the duties of their respective departments. Chief Surgeon Bear, with the regimental surgeons and their assistants, were on the field, and, by their prompt professional attention to the wounded, saved many valuable lives. A report in detail of the killed, wounded and missing, will be forwarded at an early day to the proper department. I have the honor to be, Very respectfully, M. M. Parsons,

d in 1785, and it has since been tried on the Scheldt, two turbines being used for pumps. Linnaker's hydraulic propeller, 1808, had pumps placed horizontally beneath the bottom of the vessel. The pistons were attached to hanging levers which were oscillated by the power of the steam-engine. The pistons reciprocated in longitudinal trunks parallel to the keel. In a second plan, the pumps were vertical and discharged the water through horizontal trunks. The Nautilus, furnished with Ruthven's propeller, had a trial trip on the Thames in the summer of 1868, running in company with paddle-wheel steamers of the class that ply like aquatic omnibuses up and down the river. She ran at the rate of 13.5 and 7.2 miles per hour, with and against the tide, respectively, or at an average speed of 10.35 miles per hour. She then steamed down the river, and when off the Tunnel pier, with both strong wind and tide in her favor, going at full speed, was made, by reversing the valves, to stop

s condensed in a reservoir at the surface to a degree somewhat greater than the condensation due to the depth, and passes through a pipe into the chambers c c, rendering the machine specifically lighter than water and enabling it to lift stones or other objects below. A gage indicates the amount of lifting power attained as the air is admitted, so that the supply may be cut off when the requisite power is attained. Nau′ti-lus-pro-pel′ler. A device for propelling ships, so named by Mr. Ruthven. A large iron chamber containing water is placed in a suitable part of the ship. This contains a horizontal turbinewheel rotated by a vertical shaft from the engine. The rotation of the wheel impels the water through two pipes outwardly to each side of the ship, where it escapes through two nozzles which may be directed either toward the stern or bow of the vessel, causing her either to go ahead or back, as the case may be. This motion of the nozzle is rapidly effected by means of a ha

f head, but it is supposed that the gain is greater than the loss. Chase inward and downward flow turbine. Schiele's inward-flow turbine (plan, showing scroll). The reversal of the action of the turbine driving it by steam-power in the direction contrary to its natural motion as a water-wheel forms the centrifugal or centripetal pump, according to whether the turbine be on the inward or the outward flow principle. See centrifugal pump; cen-Tripetal pump; propeller pump, Fig. 3977. Ruthven's English patent of 1849, for a hydraulic ship propeller, acting by a steam-driven turbine-wheel, ejecting the water aft, was tried in 1866 on the Water-Witch. It was termed the nautilus propeller (see page 1515). See also hydraulic propeller, pages 1149, 1150. Several tables have been constructed to indicate the powers and rates of wheels of varying diameters under different heads. They contain the sizes of the wheels in inches of diameter: the head in feet; the cubic feet of water
