ARRANGEMENT OF SEATS AND DESKS.

The desks should be faced towards a wall containing no windows, or if any they should have blinds or curtains, or the panes should be frosted. We give below a cut representing the "diagonal arrangement" of single desks, used in some of the San Francisco schools, in which the space is too small to allow aisles between each line of desks.

DESKS AND SEATS.

We give below a cut of " Warren Holt's Improved School Desk." When well made it is a durable and comfortable desk, and possesses the advantage of being made in movable sections.

The following is a cut of "Easton & Brother's Combination Desk and Seat," 725 Market Street, San Francisco. Here is what the makers claim for it. "Attention is particularly called to the design of the Combination Desk and Seat, which is tasteful, convenient, cheap, and durable. The stanchions, or end pieces, are iron, to which the wood work is fastened by screws, making the desk convenient for shipping, as it can readily be put together by any carpenter.

"The expense of this desk is but a trifle more than if made with the clumsy wood ends, while it contains, in a superior degree, all the essential requisites of a good desk and seat. The shape of the end pieces allows the pupil to get in and out of his seat easily and without noise; and a floor furnished with these desks is easily swept.
