largely on latitude changes. This area is characterized by heavy annual precipitation 
varying from 50 to 130 inches, being heaviest in the northern part of Region 1. The 
average annual temperature of these regions varies from approximately 49° in the 
north to 55° in the south. 
Region 5, which includes the western shore and islands of Puget Sound, is a warm 
one because of the moderating influence of Puget Sound, and is relatively dry because 
of the rain shadow effect of the Olympic Mountains to the southwest. 
The drier interior valleys between the Coast and the Cascade mountain ranges 
that extend from Puget Sound in Washington to the Siskiyou Mountains in Oregon, 
are divided into Regions 6 to 9. This division is made mainly on the basis of latitude— 
Region 9 on the average being somewhat drier and warmer than Region 6. 
Reference is made to Maningseed Collection maps on pages 8-11. Here it will 
be noted that the centers of seed collection zones within each region are indicated by 
numbered dots. Each dot represents a town or site of a U. S. Weather Bureau Station 
for which reliable weather records are available. The locality specification given to 
each lot of CERTIFIED MANINGSEED, therefore, means that the cones were 
collected in areas most nearly characterized for climate by the weather records per- 
taining to the numbered seed collection region and zone shown on the map. 
These specifications are indicated on the container in which the seeds are finally 
shipped. Following is a breakdown of the identification data carried on each seed 
container: 
The lot number consists of two figures: the first indicating the seed collection
