Thanks for the info! I dug up a ton of pieces in the last dump I dug so I was quite curious. I will remember that now!Nice find! These are called boat inks, they're British and date to around the turn of the 20th century. They're pretty common bottles unfortunately - I remember them as being staples of the $5 box when I lived on the west coast - but they're still fun to find and not as easy to find as you'd think they should be considering how common they are.
