Error Colossal
Note to Ad Valorem from Unto This Last by John Ruskin

The value of raw material, which has, indeed, to be deducted from the price of the labour, is not contemplated in the passages referred to, Mr. Mill having fallen into the mistake solely by pursuing the collateral results of the payment of wages to middlemen. He says:

"The consumer does not, with his own funds, pay the weaver for his day's work."

Pardon me; the consumer of the velvet pays the weaver with his own funds as much as he pays the gardener. He pays, probably, an intermediate ship-owner, velvet merchant, and shopman; pays carriage money, shop rent, damage money, time money, and care money; all these are above and beside the velvet price (just as the wages of a head gardener would be above the grass price); but the velvet is as much produced by the consumer's capital, though he does not pay for it till six months after production, as the grass is produced by his capital, though he does not pay the man who mowed and rolled it on Monday, till Saturday afternoon. I do not know if Mr. Mill's conclusion

"the capital cannot be dispensed with, the purchasers can"

has yet been reduced to practice in the City on any large scale.
