A bright fire burned in the Klondike heater, and from the kitchen came the cheerful song of a canary.

The little favourite was placed beside him on a sofa; a tea-kettle, stand, and heater were brought in, and he drank two or three cups of tea out of the finest and most precious china of Japanthat of a pure white.

Read a couple of pages every night sitting in a circle of lamp light with my back to a heater.

The heater threw out a blast of hot air.

There was a rusty box heater, littered with cigar and cigarette stubs, a desk fabricated of undressed boards, a homemade chair or two, sundry boxes standing about.

"Only the rocking-chair and the couch and that little chair you're in and the oil heater and the pictures" She ran her troubled eyes over the things enumerated, as if fearing to forget some of her few remaining possessions.

Referring to the illustrations previously published, it will be seen that the cylindrical heater of the sun motor, constructed solely for the purpose of generating steam or expanding air, is not well adapted for an exact determination of the amount of surface exposed to the action of the reflected solar rays.

It will be perceived on inspection that only part of the bottom of the cylindrical heater of the motor is acted upon by the reflected rays, and that their density diminishes gradually toward the sides of the vessel; also that owing to the imperfections of the surface of the reflecting plates the exact course of the terminal rays cannot be defined.

I have accordingly constructed an instrument of large dimensions, a polygonal reflector (see Fig. 1), composed of a series of inclined mirrors, and provided with a central heater of conical form, acted upon by the reflected radiation in such a manner that each point of its surface receives an equal amount of radiant heat in a given time.

The reflector and conical heater are sustained by a flat hub and eight radial spokes bent upward toward the ends at an angle of 45°.

The heater is composed of rolled plate iron 0.017 inch thick, and provided with bead and bottom formed of non-conducting materials.

It is scarcely necessary to state that the proportion of the ends of the conical heater should correspond with the perimeters of the reflector, hence the diameter of the upper end, at the intersection of the polygonal plane, should be to that of the lower end as 8 to 6, in order that every part may be acted upon by reflected rays of equal density.

The mean result of repeated trials, all differing but slightly, show that the energy of the direct solar rays acting on the polygonal reflector is reduced 0.235 before reaching the heater.

Agreeably to the dimensions already specified, the area of the 10-inch heater acted upon by the reflected solar rays is 331.65 square inches, the area of the 20-inch heater being 673.9 square inches.

Hence, as the 10-inch heater presents an area of 331.65 square inches, we establish the fact that the reflected solar rays, acting on the same, are diffused in the ratio of 331.65 to 0.0658, or 331.65 / 0.0658 = 5,040 to 1; the diffusion of the rays acting on the 20-inch heater being as 673.9 to 0.0658, or 673.9 / 0.0658 = 10,241 to 1.

Accordingly, the heaters of the solar pyrometer did not reach maximum temperature, the highest indication by the thermometer of the small heater being 336.5°, that of the large one being 200.5° above the surrounding air.

It will be noticed that the temperature of the large heater is proportionally higher than that of the small heater, a fact showing that the latter, owing to its higher temperature, loses more heat by radiation and convection than the former.

F. It is hardly necessary to observe that this temperature (developed by solar radiation diffused fully ten-thousandfold) must be regarded as an actual temperature, since a perfectly transparent atmosphere, and a reflector capable of transmitting the whole energy of the sun's rays to the heater, would produce the same.

The diffusion of the solar rays acting on the 20 inch heater being in the ratio of 1 to 10,241, the temperature of the solar surface cannot be less than 298.87° × 10,241 = 3,060,727°

Mrs. Landor, looking even more faded and helpless than usual, sat holding her hands at one side of the sheet-iron heater, and opposite her, his feet on the top rim of the stove, sat Craig.

A wood fire crackled cheerfully in the sheet iron heater of the tiny room where the same two people sat alone.

Vienna, with her beautiful Hotel Bristol, is such an advance in modern comfort from the best of her accommodations for travellers of a few years ago that she affords an excellent example, although for every steam-heater, modern lift, and American comfort you gain, you lose a quaintness and picturesqueness, the like of which makes Europe so worth while.
