The geographic basis of this map is a trigonometric survey by which datum points are established throughout the country; that is, base-lines are measured and a triangulation extended therefrom. This trigonometric work is executed on a scale only sufficiently refined for map-making purposes, and will not be directly useful for geodetic purposes in determining the figure of the earth.
Second, a triangulation corps engaged in extending a system of triangulation over various portions of the country from measured base-lines. Third, a topographic corps, organized into twenty-seven parties, scattered over various portions of the United States. Such, in brief outline, is the plan for the map of the United States, and the organization by which it is to be made. Mr.
The distance between the bases should be ninety feet and the four base-lines should form a square and all the angles should be right angles. The three bases should be canvas bags filled with sawdust and fastened to their positions by pegs that are driven into the ground. The home plate should if possible be a piece of whitened rubber. A board securely fastened will do.
The wooded banks, with their base-lines of flashing ice, were slipping by. Near him floated a huge, uprooted pine. A freak of the current brought the boat against it. Crawling forward, he fastened the painter to a root. The tree, deeper in the water, was travelling faster, and the painter tautened as the boat took the tow.
The souls of such men are like those weighted tumblers of pith: knocked down twenty times, on the twenty-first they stand upright, and nothing short of absolute destruction robs them of their elasticity. As now when Sebastian planned the base-lines of his new home with Josephine, and built thereon a pretty little temple of friendship armed like love.
He looked at them closely and his nerves jumped. Gosh! didn't they look big! And what big black bats! "All right, Don," said Ted. "Warm up. Take it easy. These fellows can strike out and pop up flies just as easily as anybody else." Don tried to smile as he took his place. By this time a solid wall of spectators ran along the base-lines and down toward the foul flags.
