a tariff of prices you will pay for different kinds of pavement, and we recommend as follows: If you put down concrete pavement you had better say you will pay so much per square yard for putting it down. We have looked the cities all over and find that it is the proper amount to pay; but for stone so much; for gravel so much; for asphaltum so much; and for wood so much.’ Now, that board of public works adopted the plan and that schedule of prices, and having elected if they put those various kinds of pavements down, they would put them down at those rates, they then said to all comers ‘bring in your various kinds of pavements and show us their merits, and when we have examined them we will act.’ “Then the various paving companies and patentees all over the country who had what they called good pavements, presented themselves; but in almost all cases by their attorneys. They sent men there to represent the relative merits of the pavements. A pavement company in Chicago employed Mr. Parsons, of Cleveland, as early as the month of April, 1872, to go before the board of public works and present the merits of their pavements. Mr. Parsons had nothing whatever to do with the question of prices; they had already been settled in advance by the board. Mr. Parsons was marshal of the Supreme Court at that time, and was just about running for Congress. He asked the Chief Justice of the United States whether there was any impropriety in his taking that case up and arguing it, merely because he was an appointee and under his direction, and the Chief Justice responded: ‘There was none in the world.’ He proceeded with the case until the 8th day of June, when, for the first time, I heard any thing about it. This was two days before the adjournment of Congress. On that day Mr. Parsons came to me and said to me he had an important case; he had worked a good while on it but was called away. He must leave. He did not want to lose his fee in it—was likely to lose it unless the work was completed; he must go at any rate. He asked me if I would argue the case for him; if I would examine into the merits of this pavement and make a statement of it before the board. I said, ‘I will do it if I, on examination, find the patent what it purports to be—the best wood pavement patent there is, but I can’t do it until after Congress adjourns.’ Congress adjourned two days later; the papers of patents were sent to me, modeled specimens, and documents showing where pavement had been used were forwarded to me. The investigation of the patents and the chemical analysis representing all the elements of the pavement was a laborious task and I worked at it as faithfully as any thing I ever worked at. I did it in open daylight. I have never been able to understand how any body has seen any thing in that on which to base an attack on me. I say I am to-day intellectually incapable of
