water did not cause the mortality one might expect, for in strew- 

 ing them over the bed from the scows of the oystermen very few 

 dead individuals were observed — certainly not one half of one 

 per cent. 



This alien oyster has much to contend with here. It was real- 

 ized that the cold and salt water rushing in from the Pacific — colder 

 and Salter by far than in their Atlantic home at the same time — 

 if it did not entirely prevent spawning would at least make the 

 survival of the young embryos a matter of doubt; yet it was hoped 

 that perhaps, after a number of years, the oysters might become 

 acclimated, as it were, and their spawn, inheriting their parents' 

 acquired hardiness, we might present to the people of the State a 

 new form of Oregon product in the shape of Eastern oysters hatched 

 and grown in the waters of this bay. Notwithstanding the fecun- 

 dity of this oyster, a female producing in the vicinity of sixty mil- 

 lion eggs at a spawning, it must be remembered that even under 

 the most favorable conditions in its own home, where the water 

 has in summer a fairly constant temperature of over 70° F. and 

 a salinity of 1.012 on an average, but a very small proportion of 

 this multitude survive. How much more unlikely is its survival 

 in the waters of Yaquina Bay, Oregon, where the wM-iter has seen 

 the water change from a teiujjerature of 70° F. and a saltness of 

 1.012 to a temperature of 55° and a salinity of 1.022 within six 

 hours! It was to save the young embryos from exposure to these 

 and kindred dangers that I, as a volunteer employee of the United
