It must not be forgotten that in all contracts the contractor seeks to make a profit out of the work; if there is no intermediate contractor this profit goes to the ratepayers. In most sanitary works also the men employed by the local authority are more skilled in that particular class of work than the chance men employed by a contractor, and for this and many other reasons, administration by the local authority is in most cases preferable to contracts.[252] Where tenders have been invited by advertisement or otherwise, the successful person should be written to, apprising him of the fact, and requesting him to call, sign the necessary specification, deeds, and drawings; an intimation should also be made to the unsuccessful competitors that their tenders have not been accepted. In conclusion, let me thank the authors of the following books for the useful information which I have gained in perusing them for the purposes of this work, and, let me add, they can be studied with advantage by every “Town Surveyor”: ‘American Sanitary Engineering,’ by E.
