§ 2

Both these ledgers would be constructed by combining a
number of separate net incomes, each one of which was the
balance remaining after deducting the outgo from the gross
income of the particular group of capital considered. In
other words, both ledgers would be constructed — to adopt
the phrase which was employed under capital accounts —
by the “method of balances.”
But there is also a second method of summing incomes, —
the “method of couples.” Just as the same item in capital
accounts is both asset and liability, according to the point of
view, and is, therefore, self-canceling, so the same item in
income accounts is both service and disservice, and is, therefore,
 also self-canceling. The reader may, in fact, have felt
that, in many of the examples cited, what we called disservices
 seemed to him to be services. He may have asked
himself, Why should we call rebuilding a house a disservice ?
When a carpenter and his tools repair it, do we not credit
him and them with services? Is not any production a
service? Are not, then, repairs placed on the wrong side
of the ledger? In answer it may be said that when a carpenter
 with his plane, hammer, and saw helps to rebuild a
house, we have to consider two groups of capital. One
group, the carpenter and tools, is acting on the other group,
the house. The carpenter and tools used in the process
certainly perform a service, but the house does not. Considered
 as occasioned by the house, the repairs are disservices.
 The house absorbs or soaks up these costs,
