The other parts of the bottom may be taken com-pletely down with a fine-set smoothing plane: in this manneryou may make a tenon of any breadth.

Stairs . —Are one of the most important things to be con-sidered in a building, not only with regard to the situation,but as to the design and execution: the convenience of thebuilding depends on the situation, and the elegance on thedesign and execution of the workmanship. A staircase oughtto be sufficiently lighted, and the head-way uninterrupted.The half paces and quarter paces ought to be judiciouslydistributed. The breadth of the steps ought never to bemore than 15 inches, nor less than 10, the height not morethan 7, nor less than 5 ; there are cases, however, which areexceptions to all rule. When you have the height of thestory given in feet, and the height of the step in inches, youmay throw the feet into inches, and divide the height of thestory in inches by the height of the step ; if there be noremainder, or if the remainder be less than the half of thedivisor, the quotient will show the number of steps : hut ifthe remainder be greater than the half of the divisor, youmust take one step more than the number shown by the quo-tient ; in the two latter cases, you must divide the height ofthe story by the number of steps, and the quotient will givethe exact height of a step : in the first case you have theheight of the steps at once, and this is the case whateverdescription the stairs are of. In order that people may pas 3freely, the length of the step ought never to be less than4 feet, though in town-houses, for want of room, the going ofthe stair is frequently reduced to 2^ feet.

Stairs have several varieties of structure, which dependprincipally on the situation and destination of the building.

Geometrical stairs are those which are supported by oneend being fixed in the wall, and every step in the ascenthaving an auxiliary support from that immediately below it, ■and the lowest step, consequently, from the floor. j

Dog-legged stairs are those which have no opening or well- ihole, the rail and balusters of both the progressive and return- :ing flights fall in the same vertical planes, the steps being !fixed to strings, newels, and carriages, and the ends of the ’steps of the inferior kind terminating only upon the side of !the string, without any housing. For farther particulars, seeDog-Legged Staies.

Bracket stairs are those that have an opening or well, withstrings and newels, and are supported by landings andcarriages, the brackets mitering to the ends of each riser,and fixed to the string-hoard, which is moulded below likean architrave.

The same methods must be observed as to taking the jdimensions of bracket stairs, and laying down the plan and :section, as in dog-legged stairs. In all stairs whatever, afterhaving ascertained the number of steps, take a rod, the height !of the story from the surface of the lower floor to the surfaceof the upper floor : divide the rod into as many equal parts jas there are to be risers, then if you have a level surface to jwork upon below the stair, try each one of the risers as you |go on, this will prevent any excess or defect, which even the ismallest difference will occasion ; for any error, however ,small, when multiplied, becomes of considerable magnitude,and even the difference of an inch in the last riser being toohigh or too low, will not only have a bad effect to the eye, ibut will be apt to confound persons not thinking of any such ;irregularity. In order to try the steps properly by the story- ,
