On the next day he traded 2lb of gunpowder and 1 bottle of whiskey for 5lb of caviar and 4 furs.
On third day he traded 1lb of gunpowder and 2 bottles of whiskey for 6lb of caviar and 2oz gold.

b = beads
p = powder
c = caviar
f = fur
w = whiskey
g = gold
4b+3p=4c+8f
2p+w=5c+4f
p+2w=6c+2g
multiply the 2nd equation by 2 and subtract the 3rd equation to eliminate the whiskey variable
4p+2w=10c+8f
p+2w=6c+2g
3p=4c+8f-2g
substitute that into the first equation
4b+4c+8f-2g=4c+8f
4b-2g=0
4b=2g
g=2b
2 glass beads for 1 oz gold.

bead = b
powder = p
caviar = c
fur = f
whiskey = w
gold = g
eq 1
4b+3p = 4c+8f
eq 2
2p+w = 5c+4f
eq 3
p+2w = 6c+2g
2 times (eq 2) - (eq 1)
6c = p+2w-4b
6c+4b = p+2w = 6c+2g
4b = 2g
2b = g
answer =

200 years of destruction, genocide and a decimated culture, exploited and enslaved when they quit trading gold for trinkets.
