Radiators should not be fixed directly on to the main heating pipe, but always on branches of smaller diameter leading from the flow pipe to one end of the radiator and back to the main return pipe from the other end; they may then be easily controlled by a valve placed on the branch from the flow pipe.
Compared with heating by hot water, steam-heating requires less piping, which, further, may be of much smaller diameter to attain a similar result, because of the higher temperature of the heat yielding surface.
The Javan rhinoceros (Rhinoceros sondaicus) is distinguished by its smaller size, and a different arrangement of the skin-folds (as may be seen by comparing figs.
These people came for the most part from the northern parts of the black earth zone of middle Russia, and to a smaller extent from the Lithuanian governments and the Ural governments of Perm and Vyatka.
When the water has been drawn down by pumping to a lower level its passage through the sandstone or chalk in the neighbourhood of the borehole is further resisted by the smaller length of borehole below the water; and there are many instances in which repeated lowering and increased pumping, both from wells and boreholes, have had the result of reducing the water available, after a few years, nearly to the original quantity.
