 low water mark, and at high tide, 38 to 40 feet deep, was 

 began on Christmas day, in a severe winter, in a depth of wa- 

 ter uncommonly forbidding, and in forty days carried up from 

 necessity, during the inclemency of the season, to near low 

 water mark ; the point aimed at in our original design, for 

 the work of an earlier and more temperate period."

4th 3Iay, 1803. 

 *' I most sincerely rejoice at the final success that has 

 crowned your persevering efforts, in the erection of the west- 

 ern pier ; it will afford you matter of Avell founded triumph, 

 when I tell you, that you have accomplished an undertaking: 

 unrivalled by any thing of the kind that Europe can boast of. 

 I have never in the course of my experience, or reading, 

 heard of a pier founded in such a depth of water, on an ir- 

 regular rock, affording little or no support to the piles. That 

 the work should be expensive — expensive beyond your ideas 

 — I had no doubt ; the amount thereof, with all the advanta- 

 ges derived from experience, I could not pretend to deter- 

 mine ; and if known, v/ould only have tended to produce he- 

 sitation and irresolution in a business, v/here nothing but the 

 most determined, unceasing perseverance, could enable you 

 to succeed. However, now " all your toils and dangers o'er'* 

 I heartily congratulate you on the result : not doubting but 

 the completion will prove as honourable to you as benefidiul 

 to the stockholders."
