PLEASANT LAKE (_good camping_, _tourist accommodations_, _spring water_), =155 m.=, is a small tree-fringed body of water which was called Broken Bones Lake by the Indians who camped on its shores to dry their buffalo meats. They broke the buffalo bones to remove the marrow, which they sewed into sacks of skin and preserved for winter use. Evidences of an Indian burial ground are found on a hill to the N. These burials are not in mounds, and the only excavations are those made accidentally by farmers plowing the land. At =156 m.= is the railway station of PLEASANT LAKE (1,603 alt., 33 pop.), where tribal dances were performed on the town site by a group of Indians as recently as 1883. Some of the settlers feared that the ritual was a war dance, but the Indians did no harm. At =163.5 m.= is the junction with ND 3, a graveled highway. At this crossroads is a stone cairn marking the GEOGRAPHIC CENTER OF NORTH AMERICA. In 1931 the U. S, Geological Survey determined that the geographic center of the continent is in Pierce County, N. Dak., and the marker at the highway junction is in the approximate center of the county. The survey states, "The geographic center of an area may be defined as that point on which the surface of the area would balance if it were a plane of uniform thickness, or in other words, the center of gravity of the surface.... It would not be feasible, therefore, to specify for such a large irregular area as that of North America the exact section, township and range in which the geographic center lies." Some years before 1931 Pierre, S. Dak., claimed to be the approximate center of the continent, based on the fact that two lines drawn from corner to corner of a map of North America intersected near Pierre. Right on ND 3 is RUGBY, =1 m.= (1,562 alt., 1,512 pop.), Pierce County seat, named for Rugby, England. It was platted in July 1885 and the first train arrived a month later. In the CITY HALL is a museum (_open weekdays, 9-5_) containing, among other things, Indian artifacts found in the county and Spanish-American War relics. ELLERY PARK and the tourist camp are in the western part of town. Rugby was the home of the late N. P. Lindberg, who is said to have originated the slogan, _Say It With Flowers_. It is said that in the course of a talk made at a national florists' convention in Chicago he remarked, "In North Dakota we say it with flowers." His words caught the fancy of his fellow delegates, who adopted them as a slogan. His florist shop and greenhouse, now operated by a son-in-law, are in the eastern part of town. TUNBRIDGE, =168.5 m.= (1,509 alt., 15 pop.), and BERWICK, =174.5 m.= (1,484 alt., 100 pop.), are small hamlets R. of the route. Although the latter town has a name of English origin, the Berwick _Post_, which suspended publication several years ago, was published partly in German for the large community of Russo-Germans living S. of the town.
