a frame is made of wood and iron. The cleats are placed on the two short, opposite sides, with a heavy bar of iron immediately underneath so as to clinch the nails. The planed shingles are then placed on top and nailed to the cleats with round-wire nails, which clinch automatically on the lower side as soon as they strike the iron bar. No cleats are required on the long side of small size trays, but if a larger tray is used a bar on each side may be required to give the tray sufficient strength. A good workman, after a few days of practice, can comfortably nail up four hundred trays a day. When the season is over, every tray should be nailed up and washed, or at least swept clean and stored dry. The age of a tray, if cared for, is about ten years. CALIFORNIA LYE-DIPPED RAISINS. _General Notes._--In California the dipping of raisins in solutions of lye is yet in its very infancy, and I do not think that in the whole State over ten tons of lye-dipped raisins have been placed on the market yearly. But undoubtedly this process is destined to become of considerable importance, especially in localities where the drying of the first crop is accomplished with difficulty in the open air. The first and also most important condition in producing superior dipped raisins is that the grapes should be absolutely ripe. Unripe grapes will not produce any good raisins when dipped, but will turn reddish and otherwise become inferior. _Dipping Process._--A good location for dipping raisins is by the side of an irrigation ditch, provided the water in the latter can be depended upon to flow constantly while the operation of dipping lasts. If not, the water must be procured by pumping or by means of pipes from reservoirs or water-works. Flowing water is of great importance in producing good dipped raisins, and is required for the perfect washing of the grapes. For this purpose, if no ditch is available, a large trough may be used to advantage, and so arranged that the water in it can be kept changing through a continuous flow. The following is a cheap and efficient arrangement for dipping in actual use in one of the largest raisin vineyards, and can be recommended on account of its cheapness and easy working: On one side of the trough is a stationary iron kettle with a fireplace underneath. By the trough is also placed an upright post, about five feet high, and on this balanced a horizontal beam with a double motion. It can be raised and lowered at either end, or swung to the left or right with ease. On one end of the beam is a hook on which to hang the grape bucket. On the other side of the trough is a rough assorting table. Two or more buckets are needed. These buckets are common galvanized-iron buckets, perforated thickly with holes, the latter not large enough to let any loose grapes through. In the kettle is kept constantly boiling a solution of water and potash. Soda is not suitable. The very best potash should be used in the
