Mr. Bird makes a calculation that the capacity of the Western Road can be so increased, by finishing the double track, increasing the rolling stock and adding special auxiliary force to draw its freight trains up the steep grades, that it can bring 1,797,120 tons of freight in a year. It may be presumed that he means both local and through freight. But his "calculation" is as baseless and flimsy as any of his numerous statistical bubbles which have already been pricked. The best answer to his whole argument is contained in a memorial of the Albany Board of Trade to our legislature, with some extracts from which, our review of this topic will be closed. But a few more of Mr. Bird's misrepresentations must first be exposed. On page 56 he represents Mr. Brooks as claiming that the whole through freight from the West to Boston_ eight years hence_, will amount to 448,101 tons. This estimate was made three years ago, and the words "eight years hence" were used at that time, and not now, as Mr. Bird represents. On page 50, is a list of names purporting to have been taken from the original subscription list of stockholders in the Troy and Greenfield Railroad. Mr. Otis Clapp is represented as having subscribed $200 in "services;" and Daniel S. Richardson's name is appended, with ciphers and exclamation points. The first of these misrepresentations has been exposed by Mr. Clapp, who writes to the Boston Advertiser that he never charged the company for any service, nor was ever credited by them for services, but that he did subscribe and pay $1151.43 for stock of the road. Mr. Richardson also writes to the Advertiser, and mildly suggests that he was never in any way connected with the Troy and Greenfield Railroad. On page 51, E. H. Derby is represented as being president of the Fitchburg Railroad a pure fabrication; and Alvah Crocker as having "large investments" in the same road, when its books show that at that time he owned but six shares of stock. The truth is, Mr. Bird has no hesitation or scruple in using other people's names in the same manner as he uses figures and statistics in his calculations.
