lower valley region fruit is sometimes found breaking down at the 

 core while still sound at the surface, but this tendency is not common 

 in fruit from this section.

Fruit of very highest keeping and 

 shipping quality. 



I Fruit of excellent keeping and car- 

 j rying quality. 



\ Fruit ripens evenly and is of firm 

 J texture. 



Occasionally fruit becomes overripe 

 in transit east, particularly from 

 the lower and cooler portions of 

 this region. 



Fruit holds up well and ripens 

 evenly. 



Considerable difficulty during cer- 

 tain seasons from fruit breaking 

 down in transit. 



Great difficulty in shipping; care- 

 ful precooling necessary. 



Tendency to break down at core. 



Fresh eastern shipments practi- 

 cally abandoned because of break- 

 ing down in transit. 



About the same as Santa Clara 

 Bartletts. 



Little attempt made to ship to east- 

 ern markets. Canneries take 

 total crops. 



Fruits very poor keeping; marked 

 tendency to break down inside; 

 Santa Cruz County (Watsonville) 

 Bartlett especially bad. 



1 The temperature record is not available, but the summer range is the highest of any place listed. 



2 The main pear district is somewhat cooler than Sacramento. Records are not available. 



3 The main pear district is at a much lower elevation and is warmer than the above records show. 



The Eogue River Valley district in southern Oregon produces a 

 good-shipping Bartlett pear, though considerable fruit arrives on the 

 markets in an overripe condition. This fruit approximates that from 

 the lower Sacramento Valley in carrying quality, but somewhat more 

 trouble is experienced with it, owing to a longer haul to market. 

 Most of this fruit goes east via Sacramento. The temperatures given 

 for this district are for Ashland, a markedly cooler location than the 

 main pear plantings centering about Medford.
