After this general account of the ensuing work, it might be expected perhaps, that I should proceed to the work itself; but I cannot finish this introduction without adding a few reflections on a matter very nearly connected with the present subject, and, as I conceive, neither destitute of utility nor unworthy the attention of the public: I mean the animating my countrymen, both in their public and private stations, to the encouragement of all kinds of geographical and nautical observations, and of every species of mechanical and commercial information. It is by a settled attachment to these seemingly minute particulars, that our ambitious neighbours have established some part of that power with which we are now struggling: and as we have the means in our hands of pursuing these subjects more effectually than they can, it would be a dishonour to us longer to neglect so easy and beneficial a practice. For, as we have a navy much more numerous than theirs, great part of which is always employed in very distant stations, either in the protection of our colonies and commerce, or in assisting our allies against the common enemy, this gives us frequent opportunities of furnishing ourselves with such kind of materials as are here recommended, and such as might turn greatly to our advantage either in war or peace; since, not to mention what might be expected from the officers of the navy, if their application to these subjects was properly encouraged, it would create no new expence to the government to establish a particular regulation for this purpose; as all that would be requisite would be constantly to embark, in some of our men of war which are sent on those distant cruizes, a person who, with the character of an engineer, and the skill and talents necessary to that profession, should be employed in drawing such coasts, and planning such harbours, as the ship should touch at, and in making such other observations, of all kinds, as might either prove of advantage to future navigators, or might any ways tend to promote the public service. Persons habituated to these operations, which could not fail at the same time of improving them in their proper business, would be extremely useful in many other lights besides those already mentioned, and might tend to secure our fleets from those disgraces with which their attempts against places on shore have been often attended. And, in a nation like ours, where all sciences are more eagerly and universally pursued, and better understood, than in any other part of the world, proper subjects for these employments cannot long be wanting, if due encouragement were given to them.
