the eggs, when first spawned, to he of a pale-green color, 
slightly larger than those of herring ; but becoming, after im- 
pregnation, somewhat larger than shad eggs, and losing their 
color and opaqueness, being transparent and almost invisible, 
an oily globule alone arresting the attention. 
They were placed in the hatching vessels; some in the cyl- 
inders used for shad-hatching, some in the cones and others 
in floating boxes. While the eggs were being rinsed and 
manipulated, many hundreds of thousands of them were 
poured overboard at the wharf to which the steamer was 
moored. Quite a large number of them, however, apparently 
in good condition, were placed in the hatching vessels about 
midnight on the sixth. The following table shows the tem- 
perature of the air and water during the period covered by 
the hatching of these eggs :
