It is enough for me to say that, although, if you like to review its history in detail, and examine it with a careful and malicious eye, you may find plenty that is wrong—bad contracts, faulty specifications, cases of carelessness, delay in doing what is right—still the fact remains, that it does represent a prodigious national effort to meet a Prodigious National Crisis, and I believe that 1882 the historian will review it with amazement.
