SALMON EGGS ON TRAYS READY FOR SHIPMENT 



Eggs are packed in this manner for transfer between hatcheries and for distant shipment, 

 as to foreign countries. The eggs packed in a case can, if kept cool and moist, remain out of 

 water for several weeks without impairment. One hundred thousand eggs may be carried in 

 a case.
