Wherefore take notice that I the undersigned, being the surveyor of the said urban sanitary authority, in pursuance of the statutes in that case made and provided, do hereby apportion the sum of pounds,        shillings and        pence as the proportion of the said sum of        pounds,        shillings and        pence, to be paid by you as such owner aforesaid, such apportionment being according to the frontage of your said premises, fronting, adjoining or abutting upon the said street or highway. Further take notice that the aforesaid apportionment will be binding and conclusive upon you unless within the period of three months from the day of the date of this notice you shall by written notice to the said urban sanitary authority dispute the same. Dated this          day of       , 18  . ______________________________ _Surveyor to the said Urban Sanitary Authority._ ______________________________ _Clerk of the said Urban Sanitary Authority._ There seems to be no power on the part of any owner to dispute the question as to whether the works carried out have been necessary or not, or whether the cost of the works have been excessive; the only point upon which they can go to arbitration is that as to whether the proportion settled by the surveyor is accurate or not, and this point the arbitrator is left to decide. It must not be lost sight of that there is a clause in the Public Health Act 1875, which makes the expenses so settled by the surveyor very binding upon the owner of the property in question, unless he appeals within three months from the service of the notice, as the following extract from the clause will show: . . . “Where such expenses have been settled and apportioned by the surveyor of the local authority as payable by such owner, such apportionment shall be binding and conclusive on such owner, unless within three months from service of notice on him by the local authority or their surveyor of the amount settled by the surveyor to be due from such owner, he shall by written notice dispute the same” . . . (38 & 39 Vic. c. 55, s. 257)[152] and it must also be borne in mind that the person from whom these expenses may be recovered “is the owner of the premises at the time when the work was done, not the owner to whom notice requiring the work to be done may be given” (_vide_ Fitzgerald’s Public Health Act, p. 301, 3rd edition); so that the town surveyor must be very careful to make sure that any of the property abutting on the street has not changed hands before he commences the work. After the 150th section of the Public Health Act has been carried out and a private street has been thus put into thorough repair, the urban authority may take possession of it and declare it to be a highway repairable by the inhabitants at large; the following section of the Act gives the modus operandi necessary to effect this:
