Hickory
This is the lower surface of the terminal leaflet of a hickory (Carya): note the toothed margin of the leaflet, the pinnately compound leaf in the upper right background of the photo, and the thick twig with "monkey face" leaf scar in lower left background of photo.

"Plant Galls of Illinois"
shows a similar gall on hickory made by a gall midge, Caryomyia holotricha, if that helps.

These do not look like eggs,
These do not look like eggs, they look like galls. I'm not sure which organisme is living in this galls, but my guess would be wasps...

gall
No. Galls are plant structures which are induced by insects, mites, or Bacteria (and more). These organisms "force" the plant to built a certain structure, a groth in which they live and feed. The gall is often protection and nurishment for the host.
So if you would cut the galls open, you might find an insect larvae in each of them, which will later pupate and emerge. But what you photographed is part of the plant. If you know the tree species you can google for the name of the tree and the word "gall" and you might find out what species it is which causes the galls.
It is a very fascinating story with many open questions.
Check out the guide pages:

And google for it... there is a lot of information out there.
