The use of mortises for joining the columns to the caps and sills, how- ever, should be discouraged. It reduces the bearing areas, increases the amount of work in the fitting, provides places in the lumber for the accumulation of moisture, and is in every respect an unsuitable construction, borrowed from ancient roof building, where it may do less harm, being all the time under cover and absolutely dry. 1 inclose a sketch, showing a much cheaper and better construction (tig. 6). In place of two vertical and two slanting legs, use four ver- tical legs. It is obvious that the tit of the outside slanting legs requires accurate work, consequently takes more time and money, whereas the four vertical legs being of the same length, require no special fitting. ^ Oak 'Posts.
