COMMODIOUS HOUSES WITH EARTHEN WALLS, 01 



that the vertical joints formed between each mould should 

 not be over one another, but arranged in the same manner 

 as the joints of brickwork ; this is accomplished by making 

 the lower course of wall upon the brickwork only half the 

 length of the mould, which is done by placing the end board 

 G of the mould in the middle of it. The next course over 

 this is to be made the whole length of the mould, the next 

 one only half, and so on, as shown in the figure. 



The model of the frame in possession of the Society is 

 made to a scale of an inch to a foot. The frame at large 

 is made of 1^ hich deal, ploughed and tongued together; 

 the bolts and pins or keys of iron, as are also the plates on 

 the holes in the sides of the frame. These plates are put 

 to prevent the keys from cutting into the wood, and the 

 holes from gulling and wearing. 



This sort of mould is calculated for making walls either Method of 

 fourteen or sixteen inches thick, and the model (or per- e ^ w ^ Ldrl " 

 spective view of it in the distance of plate II) shows how 

 the mould is to be applied for making the corner of a build- 

 ing of the sixteen inch wall ; the same moulds may be ap- 

 plied for a fourteen inch wall, //being the outer sides, FH 

 the inner sides. When employed for straight walls, or 

 making good between the corners of buildings, the two re- 

 turns of the frames are used in pairs, //"and F H make two 

 sets of frames. The board marked G must be of width 

 equal to the thickness of the walls to be made, and is for 

 the purpose of stopping the earth, and making ends or 

 jambs to doors or windows, or wherever wanted. The piece 

 of wood P is two inches thick, and is for the purpose of 

 making out the external sides of the moulds, from a four- 

 teen inch to a sixteen inch wall : by introducing this piece 

 between the two sides //", and putting the fixed iron pins 

 in the outer holes Z Z, and taking away the blocks under 

 the heads of the outer bolts, the sides of the frame will then 

 be sixteen inches, as under, and thereby adapted for a six- 

 teen inch wall. Fig. E are pieces of wood about l^-inch 

 square, and cut to the length of the thickness of the wall, 

 and are for gauges to be applied on the top of the bolt, 

 to keep the keys from drawing the sides too close toge- 

 ther.
