uel savers. Tests were con-ducted as described in the L922 report. A summary of the expertinents, and comments on the results, are given below. Gurney ///- II uf< r Furna& The experiments with this furnace were confined to tests of twofurnace accessories: first, the Little Wonder Fuel Saver & GasBurner; and. second, the Etobb Coal Carburetor. The former appliance was essentially a check damper, and assuch was found to he simple and efficient. A further claim hasbeen made that its use results in the improved combustion id thefurnace gases. NO improvement was noted, however, beyond thatdue to its action as a check damper. The tests on the Robb Coal Carburetor are not vet completed,hut the results obtained indicate improvement in combustion, as evidenced by the study of I he flue gas analyses. ( )n (he whole, theflue i:as analyses with this furnace, though fairly satisfactory, showroom for improvement, ami this feature is to he studied further. 24 Fourth Asm \i. Report

bo ill Scientific and Industrial Research Council of Alberta 25 Sunshine Hot-Air Funnier A scries of tests were run after the installation of the new aircalorimeters to determine the worth of the air-blast ping suppliedaround the inside of the fire pot. A summary of the results ob-tained follows: The blast ring materially assists the proper combustion of the coal by supplying air all around the fire pot just.above the fire where it is needed for the combustion of the volatilematter. Moreover, with its use, the fire picks up quicker afterfiring, and can then he more thoroughly checked, in which condition less air is drawn through the fire and more is drawn over it.Analyses show less oxygen in (he flue gases when the blast ring isin use. Incidentally it might be stated that the % grate spacing sup-plied with the furnace is too wide for the non-coking domesticcoals so far used. The loss of unburned coal to the ash pit whenthe fire is cleaned is thus too large. Other tests have shown that
