The wood of the fir is strongest in a vertical[1] position: it is remarkably well adapted for the pannels of doors, and all kinds of in-door joiners' work, whether in the Grecian, the Campanian, or the Sicilian style. The shavings of this wood when briskly planed, always curl up in circles like the tendrils of the vine. This wood, too, unites particularly well with glue: it is used in this state for making vehicles, and is found to split sooner in the solid parts than in a place where the pieces have been glued together.
