A study of hypersensitivity of high school students to the oleoresins of fifty common North Texas plants.

The following account is written to give the history of the Indians who have at one time inhabited southeast Texas, and of those who still inhabit it. The account begins with the history of each tribe as far back as any facts can be found concerning them and continues through their stay in Texas.

The following chapters attempt to show the work that has been done toward restoration, preservation, and marking of historic spots in Texas by patriotic societies, individuals, civic groups, the Centennial Commission, and other agencies. It has not been the purpose of the writer to go into details regarding every one of the sites and individual markers, especially in instances in which several of the same type were erected. In such cases a general description of the markers is given, together with a general idea of the type of inscription that appears on them. Since so much was done by the Centennial Commission, more attention has been devoted to its activities than to those of other organizations unable to carry out such an extensive program...in many instances it has been necessary to rely upon information from magazines, newspapers, Chamber of Commerce bulletins, pamphlets, and personal letters, because of lack of recorded materials. The information obtained, however, has been weighed and carefully compared with other sources on the same subject until its authenticity is assured.
