My Friend Marsh, your letter of the 20th. inspired me with new confidence in your influence and determinations. Providentialy, I had prepared and sent to you a large drawing with figures explanations amp;c. for the dome curve. I feel much agrieved, that I should be under the necessity of doing as I do with my own work. I hope the drawing will aid you tomorrow. I am exceedingly glad I made it and sent it so timely. For it will I think tend to arrest their botchings. They are of course all ready to declare that such was not their intentions but I am fully posted in all things pertaining to that work. Had I not taken the bull by the horns when I did long ere this all that curved work would have been got out and with intense amendments. They were all ready to execute what they had drawn. Knowing that I was about and informed they instantly ran to you to make pretense of desire to do as you wished. No consultation was there till I forbid their proceeding. I am thankfull they made that big drawing on the floor it is full proof of their intentions for it is entirely unlike the original or my section. They had both in their possession. I shall now try and breathe freer and next week Tuesday will go to M. and see what is being done. They are disposed to injure me but all I want is the right thing done -------------------------------- Page -------------------------------- I am armed with facts, and in due time they will get a report. Old things and new will be brought to light. I do hope that the columns will not be pieced. New investigations convince me of the absolute ridiculousness of the proceeding. That granite contains sixty per ct of Felspar, nearly two per ct. of which is water. I gave you a copy of Mr. Nicholson's drawing of St. Paul's dome. I ought to have quoted his words in relation to it and will do it now. "The following are taken from my own actual measurements viz. St. Paul's Cathedral, Islington Church" xxxx "The sides of the dome are segments of circles, the centers of which are marked in the plate, and which if continued would meet at the top and form a pointed arch" These centers of which he speaks are marked 104' the whole dome is not marked but it measures about 234'

Yours truly

T. W. Silloway

I think I informed you that on the same day that I refused to confer with Richards I wrote Powers a letter informing him that I was prepared to demonstrate the truth of all my figures, and to give him any and all explanations he desires, also full sized drawings of the dome if he wished them. I have a copy of the letters sent to him and Richards. Both contain the same facts

T. W. S.
