"THE PERFECT FURNACE. !"
LOGICAL REASONS WHY THE "RKDGEWARW IS THE BEST,

ureS or the RldgeWay FMrnace--Opeu
 Fire Pot, Easiest to Handle. Most
 Durable and Best Heating-Other
 Advantages.
 No householder should put in a furn- ace without making an effort to get the best there is in the line. The importance of having first class heater in the house, store or public building is ap- parent. One naturally wants the best. Therefore the reader who has furnace on the brain or who will have it if he gets a poor one, will thank us for call ing their attention to the Ridgway Fur mace, which is handled by T. G. White head at 36O State Street, the we'll known old established stove store, for- nerly Galpin's, and before that the Cannon stove store, MT. Whitehead is the new proprietor and he knows whereof he speaks, as he has been in the fur mace and stove business for forty years In Boston and other cities of New Eng land. MT. Whitehead makes a, notable addition to our prominent business men, For the last twenty years he has been recognized as an expert in all matters pertaining to the important art of house, store, and public building heating
 The Ridgway Furnace, which he ham, dles, is called by the hundreds of peo- pie who use 1t the perfect heater" PrinfIu lao ,,Fo olo for it over all other heaters are addi- tional fire surface, no ashes to sift, perfect combustion, no clinkers formed and all gases consumed after burning give out their heat to the best advan- tage of all concerned.
 The Ridgway Furnaces won the Highest Award and medal at the Co., lunlbia exposition of 1893; and gold medal at the Massachusetts Charitable Mechanics convention in 1892.
 Until the invention of the Ridgway Revolving Open Fire Pot there had been in the various makes of heating apparatus only two kinds of fire pots, and to-day, outside the Ridgway Furn- ace, there are only the same two kinds, namely, the least iron" and the Fbrick lined"
 Each of these two constructions has certain advantages the one over the other, and each also has certain dis advantages. For example, while on the one hand it is claimed that more heat can be obtained from the fuel in cast iron pot because, in comparison with iron, fire brick is a on-conduc- tor of heat; on the other hand the ad- vocates of brick lining claim that a better control of the fire is had in brick lined pot, with less danger of the fire becoming deadened on the edge and going out, because the brick lining prevents the cold air from chilling the fire as is the case when it strikes the sides of a cast iron pot especially if there is a low fire.
 Ridgway Open Fire Pot besides main- ta1ning features of greatest value pe- culiar to itself, embraces the advant- ages of both the cast iron and brick lined pots and overcomes their defects.
 The Ridgway open fire pot is radi- cally different from that of any other furnace Following are some of Its ad- Wantages, tested during over twenty years:
 In the Open Fire Pot the fire surface is increased to about three time the us- ual area by allowing the fire to burn outward through the openings, and thus direct radiation is had from the sides of the burning fuel in addition to radiation from the top. In this manner the entire surface of the radia- tor, combustion chamber, Is made a powerful heating surface, whereas with a solid or lined pot direct radiation from the burning fuel is had only from its top surface.
 Putting on coal in the Open Fire Pot does not smother or retard the fire, as it burns out from the sides gradually igniting the fresh fuel With solid or lined pot it is sometimes necessary to put on little coal and let that kindle before putting on more, and so spend considerable time nursing the fire
 Low fires may easily be maintained yet the furnace responds quickly in case of a sudden lowering of the tenn perature, after putting the apparatus on draft, as direct radiation Is had on all sides.
 To clear the fire the pot which rests on ball bearing or flat surfaces, is revolved by a convenient crank and as the fire turns with the fire pot, the stationary grate clears into the ash pit all the fire ashes without massing the coal. A scraper at the front clears into the ash pit anything fallen through the sides of the fire pot.
 The great durability, owing to ex- pansion construction, is shown by the fact that many are as good as new after twenty years service.
 Another thing to bear in mind IS that while in the ordinary constructor or furnaces the combustion chamber IS the space above the fire pot, in Ridg- way Furnace this space extends to the base of the fire pot tor top or ash-plt), thereby giving about twice the usual amount of this most valuable surface By the arrangements in the Rtdgway the smoke and burning gases have to travel the greatest possible distance before being dishcharged into the smoke pipe, thus saving a large per- centage of heat which ordinarily IS wasted.
 The amount of efficient radiating surface is largely increased, the fire IS under better control and slow com bustion is more easily maintained, An other advantage of this indirect t1ue Fs tba fact that ii jc Ionn+ed in the up-
