iiig a solid mass. Six large and heavy chains, are worked int€> 

 the rnasonr}'', crosswise of the pier, at the foundation; and a 

 large curb of timber, hooped with iron, surrounds the cut stone 

 at this point. Fifteen ether massive chains, fastened at pro- 

 per places, with perpendicular bolts, well wedged, are dis- 

 persed in various parts of the pier, crosswise thereof, as high 

 as low v/ater mark. The whole masonrv^ of the pier, was 

 performed (including the winter work with all its disadvaii- 

 tages) in sevent}' four working davs, after we had been seven 

 months preparing and fixing the dam. Two months of this 

 period were emploA'ed in incessant pumping, clearing and 

 combatting casualties and impediments the most embarrassing 

 and expensive. The courses of cut stone vary in depth, the 

 least course being ten inches, and the largest two feet eight 

 inches in depth," 



*' The foundation is further seciu-ed by the embankment of 

 ftone, intermixed and embodied with sand, thro%\'Ti ai'ound 

 the dam, on the bed of the river, to the height of fourteen feet. 

 The interior piling v/ill be cut off below low water mark, and 

 connected with the pier bv chains. Building stone are thrown 

 in, between this piling and the masonrv, about ten feet high., 

 the whole forming a strong barrier against anv attacks on the 

 foundation." 



^ Had we foreseen that so mPJiy casualties, difficulties, and 

 dangers vrould have attended our enterprise, we should pro- 

 bably not have hazarded the undertaking." 



" We Vv'cre convinced that the whole of our success de- 

 pended on compleating this pier ; and persevered against ca- 

 sualties and im.pediments, which frequently appeared insur- 

 mountable. It is at length accomplished, and the completion 

 of cur whole work thereby ensured. We mention, not as it 

 respects ourselves, but for the emulation and encouragement 

 of others, who may be obliged to encounter similar circum- 

 stances, that by perseverance, we have prevailed over the most 

 discouraging obstacles. A pier of solid masonry, having
