For conden-sing purposes a cooling reservoir has been constructed neara brook, some 90 yards distant from the works. The water,controlled by a sluice, can be drawn from tho brook througha settling into the reservoir. The latter is constructedof brickwork in cempnt, concrete and masonry. Efficientcooling of the condensing water is attained by the architectssystem of guide-walls, by which the water is given time topart with its heat by travelling a maximum distance beforereturning to the condenser. From the reservoir the watertravels in Large cast-iron pipes to a well—built of brickworkin cement and concrete—near the engine-house, whence it isdrawn by tho circnlating pumps to the surface condenser,from which it returns in op
