Breadth of passages, twelve feet ; length of desks, twenty-five feet and a half: total hreadth, thirty-seven feet and a half. Allowing eighteen inches to each diild, one desk will contain seventeen ; which, multiplied by seventy-three, gives 391 seats ; a number sufficiently near, since, as before mentioned, some children, in every school, are always absent, from sickness or other causes. 1562. The Dimensions of a School for 300 Children are sixty-two feet and a half by thirty-four feet, inside measure. The space is thus disposed of; length of the platform, five feet ; passages, ten feet ; nineteen desks, two feet and a half each, forty-seven feet and a half: total length, sixty-two feet and a half. Breadth of passages, ten feet ; length of desks, twenty-four feet : total breadth, thirty-four feet. As each desk will contain sixteen children, nineteen of them will seat 304. 1563. The Dimensions of a Lancasterian School for 200 Children should he Fifty-five Feet long and Twenty-eight Feet broad. Viz., platform, five feet ; passages, ten feet ; sixteen desks, two feet and a half each, forty feet : total length, fifty-five feet. Breadth of pas- sages, ton feet ; length of desks, eighteen feet : total breadth, twenty-eiglU feet. As each desk will contain twelve children, sixteen will contain one hundred and ninety-two. 1564. For a School to contain 150 Children, the length should be fifty-two and a half feet, and the breadth twenty-five feet. The width of the platform and of the passages, in this case, are the same as in the last two ; and the length of the desk will, therefore, be fifteen feet. The width occupied by each desk, including its form, being two feet and a half, there will be fifteen desks for ten children each. 1565. For a School to contain 72 Children the ground plan may be thirty feet long, and eighteen feet wide, inside mL'asure, arranged as in fig. 1383. 1383 S 2 s: 2E -J 2z_: J- ^ 1566.

The Expense of building a Schoolroom will vary in different places, accordmg to the price of materials, and other circumstances. A very comi)lete brick schoolroom, with a slated roof, capable of containing 300 children, has been built, in the neighbourhood of London, for about £^400. As the difficulty in raishig funds for the buildings has been one of the great impediments to the establishment of these schools, we recommend the following plan, which has been successfully acted upon. 1568. Tontine System of School-building. When the amount of the contract for the intended building is ascertained, let the sum be divided into a certain number of shares, each of which shall bear an interest of £5 per cent during the life of the subscriber ; but at his death, the principal is to fall into the school fund, and his proportion of interest is to be paid to the survivors. Suppose the total sum .£500, and there were "">' sub- scribers of £10 each ; the total charge of interest would he .£25, and this sum should be annually divided among the survivors equally, until the remaining one would receive :it the rate of £25 per annum upon his £10 share.
