ever, a marked difference in the appear- 

 ance, texture, and flavor of the fruit. 

 These seems to be better where the 

 drying time is relatively short, and less 

 favorable where the drying time is in- 

 creased. It must constantly be borne 

 in mind, however, that shortening the 

 drying time will not always give a 

 higher drying percentage; for if a dry, 

 parching heat is used from the start to 

 finish, the prunes will have a distinctly 

 tough skin, glossy, black color, but will 

 dry away badly. The drying time seems 

 to be of very little importance except 

 to show the presence or absence of 

 ideal conditions. If all conditions are

favorable for good evaporation, the pro- 

 cess will be fairly rapid and the drying 

 time relatively short. If the drying 

 time is abnormally long, the operator 

 should know that either his methods 

 are not the best, or else the building is 

 faulty in construction. 



There seems to be little change in 

 the appearance of the prunes during 

 the last six or eight hours of drying. As 

 the amount of moisture in the fruit be- 

 comes less, the amount evaporated in a 

 given time also becomes less and the 

 air is not cooled as rapidly as was true 

 when the prunes were giving out lots 

 of moisture. The greatest loss of mois-

ture seems to occur when the humidity 

 of the air is between ten per cent and 

 fifteen per cent. Finishing the product 

 in a high, dry, parching temperature, 

 seems to produce a less desirable fruit. 

 Economies Possible. The air at the 

 lower or finishing end of the tunnels is 

 practically dry at all times. A slight 

 increase in humidity was observed 

 when the weather was clear and warm, 

 over that noted when cold, rainy 

 weather prevailed. A greater difference 

 prevailed, however, at the upper or 

 starting end, where during clear, warm 

 weather, the humidity of the air was 

 about thirty per cent, but during cold, 



Dormant Sprag 



—controls fire blight as well as scale 



DISCARD knife and saw and paint 

 as a remedy for fire blight. You 

 can control fire blight, collar rot 

 and other orchard troubles, with Scalecide 

 — ' 'the complete dormant spray. 

 Scalecide kills the hold-over cankers that 

 cause twig and fire blight. It.cleanses and 

 disinfects the canker; it causes the old, 

 blackened bark to peel- off and new cam- 

 bium to form. No other spray does this. 



What Scalecide Does 



Scalecide kills scale, insect eggs and fun- 

 gous spores that winter over on the bark. 

 It cleans up the trees so thoroughly that 

 their increased vigor is strikingly notice- 

 able the following season. The Fall ap- 

 plication kills the adult Pear Psylla before 

 it lays its -eggs. A Spring spraying, just 

 as the buds show" green, kills aphis. Either 

 of these applications controls blight. 



Penetrates and Invigorates 



Scalecide is a. soluble and miscible oil — 

 not only an insecticide for scale, but it 

 has both fungicidal and germicidal prop- 

 erties. And because the oil globules are 

 broken up into such microscopic particles 

 they are able to penetrate the diseased bark 

 and tissues, and thus reach the bacteria 

 that cause fire blight. Scalecide actually 

 penetrates and invigorates the plant tissues. 



Saves Labor 



One barrel of Scalecide does the work of 

 three and a half barrels-of lime-sulfur. 800 



„_llons,of Scalecide (diluted 1 to 15) goes 

 farther than 1,600 gallons of diluted lime- 

 sulfur, and of course you- can put on 800 

 gallons of Scalecide in much less time 

 than 1,600 gallons of lime-sulfur. 



Protects Your Spray Pump 



Lime-sulfur eats out the valves and other 

 parts of the spray rig witbwhich it comes 

 in contact. It causes, the spray hose to 

 crack and go to pieces. Scalecide, be- 

 cause it is an oil, helps to protect the 

 spray pump from wear and tear and pro- 

 longs its life^ it makes the pump run 

 easier and develop higher pressure. 



Pleasant To Use 



Lime-sulfur burns the hands and face, 

 often injures the eyes, takes the hair off 

 the horses and eats the harness — it is ex- 

 tremely disagreeable to use. Scalecide 

 soothes the skin, does not injure the eyes, 

 improves the hair on the horses, softens 

 and cleanses harness — it is pleasant to use. 



We Own 26,000 Trees 



For ten years we have been conducting 

 spraying tests in our own large orchards, 

 which now total 26,000 trees. The most 

 important result of this practical work 

 with Scalecide in our own orchards has 

 been to discover and confirm many valu- 

 able properties of Scalecide: its invigor- 

 ating effect upon the trees; its economy; 

 its effectivenesst against fire blight; and 

 its unequalled effectiveness against insects 



and diseases of all kinds that winter on 

 the tree. We recommend Scalecide to 

 you as fruit growers.
