The account record of Thomas Hill in Dupui's general store ledger indicates that the man was likely engaged in trading activities with the Indians:

-- to 97 yds. of Nonesopritty
-- to 11 & ½ yds. of Garlix
-- to 4 yds. of half thicks
-- to 15 knives & 6 Course tooth Combs
-- to 12 Gallons of Rum
-- to 20 Barrs of Lead
-- to 50 flints

This supposition is further supported by the fact that Thomas Hill paid off his account with deer skins, with 29 lbs. of beaver skins, a wolf skin, 5 fisher skins, 2 red fox skins, 2 gray fox skins, 15 muskrat skins, 3 raccoon skins, an otter skin, and by 8 bear skins.  The fur trade was very much alive in the early days of Dupui's store:

	Muskrat skins	--	3 shillings
	Red fox skins	--	3.5 shillings
	Raccoon skins	--	4 shillings
	Otter skins	--	5 shillings
	Bear skins	--	5 shillings
	Beaver skins	--	5 shillings per pound
	Fisher skins	--	7 shillings
	Elk skin	--	23.5 shillings

Relationships with Indians are often reported in the ledger, notably in Samuel Dupui's pages.  Therein one reads of a 5 shilling purchase made on behalf of a "Squaa," a 10 shilling purchase on behalf of Paxinosa's wife (Paxinosa was a noted Shawnee chief), a 9 shilling purchase for "Joseph the Indian," multiple purchases for "Houpeck the Indian" that included rum, the purchase "to an Indian for a Cannoe," and a payment tendered by way of "3 lbs. of Gun Powder to an Indian".

The account pages of Nicholas Dupui himself also show the supply of "Meal to the Indians," and such gifts as "a felt Hatt 7s. & a Cap 3s. for Joseph the Indian".
