CHIMNEY-CAPS.

wind, at the same time that the surface is 

 smaller on which the wind can strike the 

 current, as shown in Fig. 192. A chim- 

 ney of this character may he very easily 

 made by contracting the tiers of brick, thus 

 giving to it an ornamental appearance, as 

 seen in Fisr. 193.* 



* Where different fires communicate with the same chimney, sep- 

 arate flues should be built for each fire, and kept separate in the same 

 chimney-stack, carried up independently of each other. But even 

 with this precaution, smoky rooms will not be avoided, unless the ter- 

 mination of the chimney is of the right form, of which the following 

 illustration is given in Allen's Rural Architecture : 



" Fifteen years ago we purchased and removed into a most substan- 

 tial and well-built stone house, the chimneys of which were construct- 

 ed with open fireplaces, and the flues carried up separately to the top, 

 where they all met upon the same level surface, as chimneys in past 

 times usually were built, thus. Every fireplace in 

 the house (and some of them had stoves in) smoked 

 intolerably ; so much so, that when the wind was in 

 some quarters, the fires had to be put out in every 

 room but the kitchen, which, as good luck would 

 have it, smoked less — although it did smoke there — 

 than the others. After balancing the matter in our 

 own mind some time whether we would pull down and rebuild the 

 chimneys altogether, or attempt an alteration — as we had given but lit- 

 tle thought to the subject of chimney draft, and to try an experiment 

 was the cheapest — we set to work a bricklayer, who, under our direc- 

 tion, simply built over each discharge of the several flues a separate 

 pj^ 195 *°P °^ fifteen inches high, in this wise : the remedy 



was perfect. We have had no smoke in the house 

 since, blow the wind as it may, on any and on all oc- 

 casions. The chimneys can^t smoke ; and the whole 

 expense for four chimneys, with their twelve flues, 

 was not twenty dollars ! The remedy was in giving 

 each outlet a distinct current of air all around, and on 

 every side of it."
