Appologies if this is a bit off topic but...
Working on the outside areas of my house (yorkshire dales c1830 possibly earlier), I keep coming across strange pieces of glass tube. The longest peice that I've found was broken off at about 3 inch long and was about a quarter of an inch wide. The end narrows slightly and that got me wondering whether they were some sort of pipette. If so why are there so many scattered around the grounds ? Would they have had a use in farming ? Any ideas ?
