Thespace then between the iron and this point is that whichmay be filled by the wooden armature, being careful to 88 Modelling allow for three or four inches of clay, so that the armatureshall not be too near the surface and in the way during theprogress of the work. The same must be done at different points around theiron, that is at the centre and the two ends on either this way six points will have been established, determin-.

The space left between the iron and the extremity ofthese points is to be filled by a wooden armature ; which isto be made as follows. Take two planks 3 feet 6 incheslong, 9 inches wide and 2 inches thick ; make two holes inthem corresponding exactly with those in the horizontalbranch of the iron. To do this correctly place the plankagainst the iron, and from the other side of the iron pass apencil through the holes, making a mark on the gives the exact places where the two holes are to- Modelling 89 be made in the plank. The same is then done for theother plank. After this, pass bolts first through the holes ofthe plank which is going to be placed on the more important sideof the composition, then through the holes in the iron, thenthrough the holes of the plank on the other side, and screw thewhole firmly together, being careful that the nuts are on t
