It will make considerable difference whether or not there is glass i% the ex- posed walls of the houses, and we would be better able to offer helpful sug- gestions if a description of the present heating system had been given, since much depends upon the size and ef- ficiency of the boiler and the piping, and whether it is an open or closed system.

Metropolitan Patented Boilers will beat a given amonnt of water quicker, with less fuel and leas attention than any other boiler on the market. The remarkable heatlngr efficiency and quick steaming qualities of these boilers are due to their large and effective heatiniir surface. Just a few points of Metropolitan Patented Boiler merit:—
