"I see by the papers that the subject of the Bank is likely to be renewed. I should like to know when it will come on, as I have some thought of coming down at that time, if I can. "I see by the papers that the Agricultural Society have presented a petition to the house respecting building a Bridge over the Schuylkill--on a model prepared for that purpose. In this I think they are too hasty. I have already constructed a model of a Bridge of Cast Iron, consisting of one arch. I am now making another of wrought Iron of one arch, but on a different Plan. I expect to finish it in about three weeks and shall send it first to Philadelphia. I have no opinion of any Bridge over the Schuylkill that is to be erected on piers--the sinking of piers will sink more money than they have any Idea of and will not stand when done. But there is another point they have not taken into their consideration; which is, that the sinking three piers in the middle of the river, large and powerful enough to resist the ice, will cause such an alteration in the bed and channel of the river that there is no saying what course it may take, or whether it will not force a new channel somewhere else."* * I am indebted for this letter to Mr. Simon Grata of Philadelphia. To George Clymer, Esquire, "to be left at the Bank, Philadelphia." Written at Bordentown, November 19th.--"I observe by the minutes that the Agricultural Society have presented a petition to the house for an act of incorporation for the purpose of erecting a bridge over the Schuylkill on a model in their possession. I hope this business will not be gone into too hastily. A Bridge on piers will never answer for that river, they may sink money but they never will sink piers that will stand. But admitting that the piers do stand--they will cause such an alteration in the Bed and channel of the river, as will most probable alter its course either to divide the channel, and require two bridges or cause it to force a new channel in some other part. It is a matter of more hazard than they are aware of the altering by obstructions the bed and channel of a River; the water must go somewhere--the force of the freshets and the Ice is very great now but will be much greater then. "I am finishing as fast as I can my new model of an Iron Bridge of one arch which if it answers, as I have no doubt but it will, the whole difficulty of erecting Bridges over that river, or others of like circumstances, will be removed, and the expense not greater, (and I believe not so great) as the sum mentioned by Mr. Morris in the house, and I am sure will stand four times as long or as much longer as Iron is more durable than wood. I mention these circumstances to you that you may be informed of them--and not let the matter proceed so far as to put the Agricultural Society in a difficult situation at last.
