Pine cones are admirable for lighting a fire; and you will find the gloomy Scotch pines, which have so annoyed you with their shade, may be useful in this respect, as producing an article of domestic economy. If any of your chimneys should smoke, the usual remedy is contracting the mouth of the chimney, or raising it higher by the addition of a chimney-pot. The last is a most unsightly remedy, and I hope you will not have occasion to try it. Indeed, old houses seldom smoke, unless their chimneys are damp for want of use, or that birds have built in them; though nothing can be more common than to have smoky chimneys in modern houses. One reason, I believe, is, that newly built chimneys very often smoke because they have not been properly cored; that is, the projecting pieces of mortar, &c., which are formed inside the chimney while it is building, have not been removed, and prevent the proper ascent of the smoke. Another common fault in modern fireplaces is, that they are too shallow to allow sufficient space for the grate; and, when the grate is set too far forward into the room, it is evident that a very strong draught will be required to draw the smoke up the chimney. Neither of these faults is common in old houses; in them the chimneys are generally as smooth inside as the walls of the room, and the fireplaces are usually two feet deep, or even more, instead of being only nine inches, as I am told is the case with some modern villas. I say nothing about stoves, as I confess myself prejudiced against them, from the numerous fires they have occasioned; and I think open fireplaces not only safer and more agreeable, but much more conducive to health, as they aid in ventilating the apartments, and without a constant change of air there can be neither health nor happiness. In speaking of the different kinds of fuel, I forgot to mention peat and charcoal, but you will find these more useful in the kitchen than in the parlour; and coke I would not advise you to employ, on account of its close unpleasant smell.
