Since the foregoing pages were written, Mr Bird has published and distributed another pamphlet, the remarkable audacity of which challenges our attention. If one half of the assertions it contains were true, if one half of its calculations and estimates could be demonstrated, the Hoosac Tunnel ought to be abandoned at once, as the greatest folly of the nineteenth century, and its ruins sacredly preserved as a monument to coming generations of a monstrous popular delusion: and if the epithets--swindlers, tricksters, liars, plunderers, thieves, ingrates, rascals, traitors and fools--which Mr. F. W. Bird, of Walpole, so freely and indiscriminately applies to everybody who has advocated or favored the building of this Tunnel, were deserved; then a very large proportion of several legislatures, a majority of several executive councils, and many distinguished citizens and state officers, including the late governor and attorney general, ought to be lodged for the remainder of their days either in the state prison, or the asylums for idiots. This last publication of Bird's is mainly a repetition, "with embellishments," of his previous pamphlet, with the addition of a preface purporting to be the history of tunnel legislation to the beginning of the present year, a string of calculations and conjectures as to the capacity of the Western Railroad to transport ( provided it were properly managed, and the double track completed) all the Western freight and travel for all future time, and several pages of coarse denunciation of Mr. Brooks, chairman of the Tunnel Commissioners, and the manner in which he has managed the trust committed to him. The subdivisions of these subjects are:-- 1st. Tunnel Legislation. 2d. Abuse of Mr. Brooks. 3d. Power Drills. 4th. The Deerfield Dam. 5th. "Porridge." 6th. The Western compared with the Tunnel line. 7th. The Possible Capacity of the Western Road. 8th. The Cost and Time required to Complete the Tunnel. It is not our purpose to expose _all_ the misrepresentations and perversion of facts to which Mr. Bird has resorted in the treatment of his subject; but only enough of them to show what disreputable means the foes of the Tunnel are capable of using in order to deceive the community. Late results in the progress of work at the mountain, and in the perfection of machinery, will enable us to illustrate the utter absurdity of several of the most important of Mr. Bird's calculations, or rather speculations, and enable the reader to judge what reliance can be placed upon any of them.
