ALBERT C. RITCHIE, GOVERNOR. 1483

will be heard. Such notice may be mailed to the last known
address of the owner, or served in person upon any adult
occupying the premises, of in the case of vacant or unimproved
property, posted upon the premises. The classification of and
benefit assessed against any property as made by the Commis-
sioners of Delmar shall be final, subject only to revision at said
hearing, and subject further to an appeal upon all matters of
law and fact to the Circuit Court of Wicomico County, said ap-
peal to be taken within thirty days after decision by said com-
missioners. The Commissioners may change the classification
of properties from time to time, as. said properties change in the
uses to which they are put. Said benefits shall be levied for
sewerage construction upon the number of front feet abutting
upon the street, lane, alley or right of way in which the sewer
is placed; provided, however, that no lot shall be assessed on
more than one side, that corner lots in this class shall be as-
sessed on that frontage towards which the building does or
would naturally face, and that all lots in this class shall be
assessed for their full frontage even though a sewer may not
extend along the full length of any boundary; and, provided,
further, that in the case of irregular shaped lots, and shallow
lots fronting on more than one street, the Mayor and Council
may determine upon for assessment, and may assess, such
length of frontage as they deem reasonable and fair. Front
foot benefit charges for sewerage construction shall be uniform
for each class of property throughout the town. The amount
of the charge per front foot for each class of property for
sewers shall be determined from time to time by the Commis-
sioners of Delmar as costs and conditions require. Said bene-
fit charges shall be paid annually beginning in the year such
construction is begun, by all properties located as above speci-
fied, for a period of years co-extensive with the period of
maturity of the bonds out of the proceeds of which such con-
struction was done; provided, however, that any property
owner may, at his option, within one year from the time said
front foot assessment or benefit charge is levied, extinguish
the same by the payment in cash, in one sum, of the proportion
of the estimated cost of the project of which the construction
abutting upon his property is a part, represented by the number
of front feet with which he is assessed, with interest at the
rate of 6 per cent, per annum, from the date of said levy, less
any annual payment that may have been paid thereon. The
Commissioners, however, in estimating said cost for the pur-
pose of extinguishment, may add thereto a reasonable margin
