The effect of drying time on the drying 

 percentage or weight per bushel is not 

 very marked. For instance, a difference 

 in drying time from 29 hours to 77 

 hours gave a difference in dry per cent 

 of only 4 per cent in favor of the 

 shorter time. There seems to be little 

 or no difference in drying percentage so 

 long as the drying time is kept below 

 30 hours and above 15 hours. An addi- 

 tional advantage of the shorter time is 

 noted in the more attractive appearance 

 of the finished product. In order to 

 obtain a drying time within the limits 

 noted above the following conditions 

 were found essential: A temperature 

 in the beginning not lower than 120 and 

 preferably as high as 140 degrees. A 

 finishing temperature not higher than 

 180 degrees and not lower than 165 de- 

 grees. The maximum temperature for 

 the finish would depend largely on the 

 circulation of air. At no time should 

 the circulation of air drop below 660 

 feet per minute, and while we have no 

 definite figures to give as to how high 

 a circulation would be desirable, we 

 have found that with the air circulation 

 as rapid as 1,000 to 1,200 feet per min- 

 ute, very excellent results were ob- 

 tained. Another interesting fact in con- 

 nection with the circulation of air is to 

 the effect that the humidity of the air 

 as it passes out is not sufficient to hin- 

 der its use a second, third or even 

 greater number of times. In other 

 words, there is no reason from a 

 moisture standpoint why the air should 

 not be returned to the furnace pit again 

 and again. Since in most cases this 

 could be returned at a temperature 

 fully twice as high as that of the out- 

 side temperature. By reheating, with 

 perhaps a small amount of new air 

 added, a great saving of fuel would be 

 made. The question in connection with 

 this, however, is, can a means be ob- 

 tained of returning this air to the fur- 

 nace at a cost small enough to warrant 

 its adoption? Summing up, then, some 

 of the facts in relation to prune evapo- 

 ration we find it possible to decrease 

 our cost of harvesting and increase our 

 profits by allowing the prunes to ripen 

 more fully. We can make more at- 

 tractive products by omitting the use of 

 lye and substituting a more rapid cir- 

 culation of air in the evaporator. Be- 

 yond this there is still considerable 

 experimental work to be done, and we 

 trust that the Oregon Agricultural Col- 

 lege, with its new facility for carrying 

 on the work, will be able to render 

 some valuable assistance to the prune 

 growers in the near future. 



Order Spray Material Now 



Insect pests and fungous diseases arc 

 always with us and must be combatted. 

 Due to transportation difficulties and a 

 possible shortage of spray material, 

 growers are urged to consider their 

 seasonal needs and order their insecti- 

 cides and fungicides now. Traffic con- 

 gestion and freight embargoes threaten 

 seriously to interfere, if not largely to 

 prevent the timely shipment of large 

 quantities of fungicides and insecti- 

 cides for use in seed treatment and 

 early summer spraying and (lusting.
