To quickly assess the difficulty of the text, read a short excerpt:
requiring some considerable skill, and involving many practical details. Within the present limits we may note briefly the fol- lowing points : Two general methods of procedure are open: (i.) A solid block may be glued up, and then pared down as tested by concave moulds cut out to fit the form of the sections, and applied to the model at the corresponding stations. In this manner the block is reduced to the desired form at a series of regularly spaced stations. The intermediate parts are then b...rought down, and the whole faired up. (2.) A series of "lifts,'' or boards of thickness to represent the space between the water lines., is prepared, and the water lines laid out one on each. The lifts are then cut out, each to its own foi-tti, and these are then pegged together or glued up, as may be preferred. The corners are then brought down so that the form is smooth and continuous and with water lines as deter-, mined. The indications of such a model will often suggest slight changes in the form^ and this may be done on the drawing board and followed up on the model, until between the two the resulting form seems to satisfy the judgment taken from all possible points of view.
