Res′er-voir.
1. A pond for containing a supply of water for canal supply, irrigation, or the use of dwellers in cities.
A reservoir erected by Nebuchadnezzar at Sippara was 140 miles in circumference.
The lake of Maeris, constructed by the Pharaoh of that name to receive the superabundant waters of the
Nile at the time of overflow, and afterward yield them for prolonged irrigation, was described by
Diodorus Siculus (60 B. C.) as existing till his day. The circuit he gives, 3,600 furlongs, is almost incredible.
The canal connecting it with the river was 80 furlongs long and 300 feet wide.
Sluices commanded the water-way by opening and shutting.
The reservoir on
Mill River, Mass., which burst with immense damage to life and property, May 16, 1874, was an artificial lake between high hills.
The confining dam at the lower end was a stone-wall five and a half feet thick at bottom, three feet at the top, and 25 feet high.
This wall was about 300 feet long built of uncut stone from a foundation four feet below the level of the ground at the lower side, and was backed on the upper side with a bank of earth interwoven with branches of trees.
The dam had been built eight years at the time of the catastrophe.
See dam.
2. An attachment to a stove or range to hold hot water.
It is heated by proximity to the stove itself or to the stovepipe.
In
Fig. 4268, it is behind the stove, having a flue
b b around and beneath it.

Reservoir-stove. |
In
Fig. 4269, it is on top of the stove.
In a modification of the latter form the boiler is made to surround the stovepipe.
The reservoirs of ranges are usually vertical iron boilers, connected by pipes with the water supply of the city.
The water from the main passes through pipes in the fire-chamber, or through a water-back, and thence to the boiler.
A pipe from the boiler proceeds to the sink to supply hot water at that point, a branch leading to the bath-room and another to the laundry.
