5The qualities of trees vary exceedingly, and are very dissimilar, as those of the oak, the elm, the poplar, the cypress, the fir, and others chiefly used in buildings. The oak, for instance, is useful where the fir would be improper; and so with respect to the cypress and the elm. Nor do the others differ less widely, each, from the different nature of its elements, being differently suited to similar applications in building.
5Trees vary and are unlike one another in their qualities. Thus it is with the oak, elm, poplar, cypress, fir, and the others which are most suitable to use in buildings. The oak, for instance, has not the efficacy of the fir, nor the cypress that of the elm. Nor in the case of other trees, is it natural that they should be alike; but the individual kinds are effective in building, some in one way, some in another, owing to the different properties of their elements.
