From all appearances the excavation will probably consist chiefly of compact sandstone; so that very little interference will be experienced from water and no arching will be necessary: it may nevertheless be proper to introduce this element into the comparison of the Bids. The following statement exhibits the influence of this circumstance on the bids, under the supposition that one half of the Tunnel will require arching with brick.
