8-oiince glasses, retailing at about 15 cents a glass. The price of dry 

 apple pomace in January, 1921, was 2^ cents a pound ; on this basis 

 grape pomace should cost about a cent less. Since the only other 

 ingredient is sugar, it follows that the prices of the two finished 

 products should be approximately the same. 



There should be no difficult}' in marketing this jelly, since grape 

 jelly is well liked, and the reason it does not fill a greater place in 

 the dietar}^ is largely on account of the high price. If, therefore, 

 grape skins are utilized for this purpose it is evident that the jelly 

 could be sold about as cheaply as apple jelly and yet return a satis- 

 factory profit. The wholesale value of the total quantity of jelly 

 capable of being manufactured from the grape skins available an- 

 nually (3,300 tons) would be more than $2,000,000. 



The net profit in handling grape waste will vary according to the 

 plan of utilization adopted. These plans maybe stated as follows : 



(1) To separate the seed from the wet pomace at each factory, sell the seed, 

 and manufacture the jelly immediately from the wet skins. 



(2) To dry the pomace, separate and sell the seed, and manufacture the jelly 

 from the dry skins during the season when the presses would otherwise be idle. 



(3) To dry the pomace, separate the seed and skins, and sell both. 



Plan No. 1. — Since 1 dozen glasses of jelly can be made from 

 about 4 pounds of wet skins, 1,000 tons of grapes (producing 150 

 tons of wet skins) would yield approximately 75,000 dozen 8-ounce 

 glasses. At a selling price of $1.50 a dozen the gross returns would 

 be $112,500. The cost to manufacture this quantity of jelly (which 

 will be given in detail later) amounts to $87,000, leaving a net profit 

 on the jelly of $25,500. A thousand tons of grapes produces about 

 50 tons of seed, which would bring approximately $500. The total 

 profit, therefore, in plan No. 1 would be $26,000. 



Plan No. 2. — As in plan No. 1, the yield of jelly from 1,000 tons 

 of grapes would be approximately 75,000 dozen glasses and the gross 

 returns the same, $112,500. To the" cost for manufacturing the jelly 

 ($87,000) must be added that for drjang and bagging the pomace 

 (200 tons), which is approximately $1,800, making the total cost 

 $88,000. The net profit on the jelly in this case would therefore be 

 $23,700. Here again the seed would bring approximately $500, mak- 

 ing a total profit in plan No. 2 of $24,200. 



Although plan No. 2 is not quite as profitable as plan No. 1, it is 

 far more practicable, since it utilizes the presses during the winter 

 months when otherwise they would be idle. 



Plan No. 3. — Here the pomace is dried and both seed and skins 

 are sold, so that no cost for manufacture is involved. The dry 

 sldns, delivered at a utilization center (jelly factory), would bring 

 about $24 a ton. This includes $9 a ton for drying and $5 a ton for 

 hauling, leaving a net profit of $10 a ton, which on 75 tons of dried 

 skins (150 tons of wet skins) would equal $750. To this must be
