county. They shall also perform such other duties with respect
to the public roads in their respective districts, as the High-
ways Commission may, by its regulations or orders, prescribe.
No road supervisor shall have any pecuniary interest in any
contract, or shall furnish any team for any road work in the
county, except in such cases as the Highways Commission
shall expressly authorize in advance by an order duly entered
on its records. Except as aforesaid, every road supervisor,
when presenting for payment any bill for the hire of horses
and carts or wagons, shall append thereto an affidavit that he
is not interested, directly or indirectly, in the payment of the
amounts charged for such hire of horses and carts or wagons,
or for any material furnished. Said road supervisors shall
keep books, showing in detail the expenditures made by them
or under their supervision, on each road in their respective
districts, including the cost of all material used on the roads
and the labor expended, and shall furnish on or before the
tenth of each month, to the Baltimore County Roads Engineer,
a copy of such itemized statement of their expenditures for
the month just passed; said Engineer shall examine said bills,
and if he finds the same correct, and the items properly allowa-
ble, shall mark the same approved and deliver the same to the
Highways Commission for its further approval and payment,
as hereinafter, provided. On or before the tenth day of Decem-
ber in each and every year, said road supervisors shall submit
to the Baltimore County Roads Engineer a written report
showing the conditions of the roads in their respective districts,
the improvements that have been made during the preceding
year, and the amounts and kinds of material used on each road,
with a detailed statement of its cost and the amount and cost
of hard material and labor on each road. Each road supervisor
shall be entitled to receive as compensation for the duties per-
formed by him under this sub-title an amount equal to ten per
cent, of the total amount of the district allotted, as here-
inafter provided, to his particular district, exclusive of any
allowances made to such district from the general or other
funds expended in such district; provided, that in those dis-
tricts where compensation on such basis would amount to less
than two hundred and fifty dollars, they shall be allowed an
annual salary of two hundred and fifty dollars, and that in
those cases where compensation on such basis would amount to
more than one thousand dollars, they shall be allowed an
annual salary of one thousand dollars, said allowance and
salaries to be received by them in lieu of all other compensa-
tion for the duties performed by them under this sub-title.
Such compensation shall be paid in monthly or quarterly in-
