trays in piles, but if cooler, moister weather prevails, the trays 
must be spread out. The product is a handsome amber color. 
An oil-dip is also being profitably used with Thompsons 
Seedless :— 
One quart olive oil; 34 pound Greenbank soda and 3 quarts 
water are made into an emulsion, and then reduced with to 
gallons water in the dipping tank, adding more soda to get lye- 
strength enough to cut the skins, and more soda has to be 
added from time to time to keep up the strength. The grapes 
are dipped in this solution and sulphured to the proper color. 
Drying of wine grapes for sale at the East or in Europe is 
practised. They can be profitably produced at quite a low price, 
in miuch the same way that raisins are made but with less care. 
GRAPE SYRUP. 
The manufacture of grape syrup, which was formerly of con- 
siderable prominence as a means of disposing of wine grapes, 
has recently received less attention because of low prices in com- 
petition with the vast amount of syrup available from the sugar 
refineries. As the source of sugar is now so largely the beet, 
grape syrup may again be profitable in the future. Open evap- 
orating pans are chiefly used.
