The general Post Office Department has continued, upon the strength of its own resources, to facilitate the means of communication between the various portions of the Union with increased activity. The method, however, in which the accounts of the transportation of the mail have always been kept appears to have presented an imperfect view of its expenses. It has recently been discovered that from the earliest records of the Department the annual statements have been calculated to exhibit an amount considerably short of the actual expense incurred for that service. These illusory statements, together with the expense of carrying into effect the law of the last session of Congress establishing new mail routes, and a disposition on the part of the head of the Department to gratify the wishes of the public in the extension of mail facilities, have induced him to incur responsibilities for their improvement beyond what the current resources of the Department would sustain. As soon as he had discovered the imperfection of the method he caused an investigation to be made of its results and applied the proper remedy to correct the evil. It became necessary for him to withdraw some of the improvements which he had made to bring the expenses of the Department within its own resources. These expenses were incurred for the public good, and the public have enjoyed their benefit. They are now but partially suspended, and that where they may be discontinued with the least inconvenience to the country. The progressive increase in the income from postages has equaled the highest expectations, and it affords demonstrative evidence of the growing importance and great utility of this Department. The details are exhibited in the accompanying report of the Post Master General. The many distressing accidents which have of late occurred in that portion of our navigation carried on by the use of steam power deserve the immediate and unremitting attention of the constituted authorities of the country. The fact that the number of those fatal disasters is constantly increasing, not withstanding the great improvements which are every where made in the machinery employed and in the rapid advances which have made in that branch of science, shows very clearly that they are in a great degree the result of criminal negligence on the part of those by whom the vessels are navigated and to whose care and attention the lives and property of our citizens are so extensively intrusted. That these evils may be greatly lessened, if not substantially removed, by means of precautionary and penal legislation seems to be highly probably. So far, therefore, as the subject can be regarded as within the constitutional purview of Congress I earnestly recommend it to your prompt and serious consideration.
