How much tea, sugar, soap, candles, bread, butter, bacon, could Mrs.Welden use in a week?
It was not very easy to find out the exact quantities, as Mrs.Welden's estimates of such things had been based, during her entire existence, upon calculation as to how little, not how much she could use.
When Betty suggested a pound of tea, a half pound--the old woman smiled at the innocent ignorance the suggestion of such reckless profusion implied.
"Oh, no! Bless you, miss, no! I couldn't never do away with it.

A quarter, miss--that'd be plenty--a quarter." Mrs.Welden's idea of "the best," was that at two shillings a pound.

A pound of sugar would be twopence, Mrs.Welden would use half a pound (the riotous extravagance of two cents).

Half a pound of butter, "Good tub butter, miss," would be ten pence three farthings a pound.

Soap, candles, bacon, bread, coal, wood, in the quantities required by Mrs.
Welden, might, with the addition of rent, amount to the dizzying height of eight or ten shillings.
