Having built a house with permanent rafters, and desiring to glaze it in such a manner that the glass could be easily removed in the summer, I stretched ordinary candle wicking from end to end of the rafters, letting it lie on the shoulder of the rabbet, and bedding the glass on this, not lapping it, but laying it with one end against the other and tacking it down with ordinary tacks, four to each pane. I have in this the closest roof in a range of eight houses glazed with putty. The work of removal, as any practical man will see, will be very light, with but little danger of breakage, and the work of re-glazing will be as light as at first.
