-We are of opinion that the objection to the assessment, in this case, that it included an amount, as incidental expenses, for engineering and printing, was waived by a failure to appeal to the board of supervisors. (§ 12 of the act of 1872; Stats. 1871-2, p. 815.)

We are also of the opinion that the resolution of intention sufficiently described the work which the board of supervisors desired to have done.

Judgment and order denying a new trial affirmed.
