It is thought that attention is also due to the improvement of this city. The communication between the public buildings and in various other parts and the grounds around those buildings require it. It is presumed also that the completion of the canal from the Tiber to the Eastern Branch would have a very salutary effect. Great exertions have been made and expenses incurred by the citizens in improvements of various kinds; but those which are suggested belong exclusively to the Government, or are of a nature to require expenditures beyond their resources. The public lots which are still for sale would, it is not doubted, be more than adequate for these purposes. From the view above presented it is manifest that the situation of the United States is in the highest degree prosperous and happy. There is no object which as a people we can desire which we do not possess or which is not within our reach. Blessed with governments the happiest which the world ever knew, with no distinct orders in society or divided interests in any portion of the vast territory over which their dominion extends, we have every motive to cling together which can animate a virtuous and enlightened people. The great object is to preserve these blessings, and to hand them down to the latest posterity. Our experience ought to satisfy us that our progress under the most correct and provident policy will not be exempt from danger. Our institutions form an important epoch in the history of the civilized world. On their preservation and in their utmost purity everything will depend. Extending as our interests do to every part of the inhabited globe and to every sea to which our citizens are carried by their industry and enterprise, to which they are invited by the wants of others, and have a right to go, we must either protect them in the enjoyment of their rights or abandon them in certain events to waste and desolation. Our attitude is highly interesting as relates to other powers, and particularly to our southern neighbors. We have duties to perform with regard to all to which we must be faithful. To every kind of danger we should pay the most vigilant and unceasing attention, remove the cause where it may be practicable, and be prepared to meet it when inevitable.
