in commercial pomolog}'. We grow a few native plums 

 both hortulanas and Americansas and when there is any sale 

 for these the prices vary from six to twelve cents per gallon. 

 We tried manufacturing some of these plums just to find out 

 what could be done. Our results were fairly uniform and 

 gave the following figures. 



1 gal. plums @ 12c. 12e. 



6 lb. sugar @ 5c. 30c. 



10 glasses @ 2c. 20c. 



Total cost 62c. 



For products we had six 8-ounce glasses of jelly and 

 four 8-ounce glasses of marmalade. These products have a 

 retail value as follows 



Plum jelly, 2oc. per gla.-s 



Plum marmalade 10c. per glasr^. 

 making a total retail value of .+1.90, which would leave $1.28 

 to cover cost of labor, fuel, marketing expenses and for 

 profit. 



Then too, our second grade grapes usually sell at about 

 2y2C. per pound. We tried several experiments with these, 

 using the first run for juice, the second for jelly, and the 

 pulps for butter. The addition of a small amount of apple 

 ,niice improved the jelly while the apple pulp gave the butter 

 better quality. The whole result may be best shown as fol- 

 lows.

 *If the juice were solcl for ten cents per bottle (which is 

 certainly cheap enough), it alone would pay for all materials 

 used. " Evidently tlie'jeljy and butter would pay for labor
