Excerpt from Main Drainage Works of the City of Boston: Massachusetts, U. S. A This brief description of the Main Drainage Works, of Bos ton, aims to record, for the benefit of engineers, an account of the engineering problems involved and the methods'of construc tion adopted. It also aims to give to the tax-payers and gen eral public a descriptive account of why the large appropriation for An Improved System of Sewerage was needed, and how it has been spent. By attempting to accomplish both of these purposes it fulfils neither of them adequately; since one class of readers will find it too technical, and the other too deficient in detail. It has been prepared amid pressing engagements, and to save time the writer has not hesitated to borrow freely from previous reports, by himself and others. Traces of such compilation will, doubtless, be noticed by the discerning. It is hoped that a fair idea of the works can be obtained from the illustrations; and that the description, even by its defects, may encourage other engineers to publish, as they too seldom do, accounts of works with which they have been connected.
