Wilson's quarter century in photography : a collection of hints on practical photography which form a complete text-book of the art . develop a plate, the overflow of the developing solution at onceflows down the tube into the reservoir, and is saved; as is also the solution drained ofton the completion of the development. Then the waste being turned on, the opening tothe reservoir is closed, while that to the waste is opened, and the water flows freelyaway. For intensifying (and also for fixing, should cyanide be used), the same operationis gone through, and the solutions are thus saved without any trouble or loss of time tothe operator. A sink of this form possesses also the following advantages: first, there is no splashing,on account of the sloping sides upon which the water falls; and, secondly, that as thesink is kept drained, and is, in fact, washed out in the act of washing each plate, noinjurious fumes are likely to arise to cause the ill health of the operator, as in the oldform of sink, when the solutions were allowed to mix freely in an open vessel which wasnever perfectly freed from them.—J. C. DARK ROOM CONTRIVANCES. 263 tank, and eighteen inches above it, permits the negatives to be taken out, andthe droppings to fall into the wasliing tank, thus avoiding droppings of hypoon the floor. The developing tank is supplied with one faucet, and the wash-ing tank with two. 110. On the east side is a table (8) on which are kept the plate this table and the tanks 5, 6, and 7, is a long tank for plate-washing,12 inches deep and 5 feet long; an inclined false bottom reaches from end toend, within 5 inches of the top at the back, inclining to the bottom at the frontedge. Along the whole length is a perforated water pipe which casts a con-tinuous stream over the plates as they lie one above the other, edge to edge onthe inclined plane. Thus many plates may be waslied at one time. Over the tanks are nails to hang the negatives upon. All par
