    6. Long-leaf pine tapped for turpentine, which is extracted over a period of two or three years before the timber is cut. Region 1.

    7. Seedling long-leaf on cut-over forest. Note the rejected relict trees which have furnished the seed. Region 1.

    8. Salt grass on the coastal prairie. Low shrubs of huisache appear in front and rear of the figure. Region 2.

    9. Huajillo, prickly pear, blackbrush, and yucca in a typical chaparral mixture. Region 4.

    10. Looking across Green Gulch to Lost Mine Peak in the background, Chisos Mountains. The steep slope below the cliffs is covered with oak; the bunch growth in the foreground valley floor is slender bear grass and sotol. Region 8.

Texas Vegetation

ON the pages of this section the reader will find the follow ing:

1. A map representing an attempt by the author to delineate his concept of the major vegetational regions of the state, eighteen in number.

2. A very brief summary account of the dominant features to be found in each region.

3. A list of genera of ferns and flowering plants (seed plants) to be found in the state, based on collections in the herbarium of the University of Texas, giving the regions in which each has been found. This list, necessarily incomplete, includes several genera not heretofore of published record for Texas.

4. Such illustrations as limitations will permit

By these means it is hoped to convey to the mind of one not familiar with the various regions some idea of their vegetational physiognomy 1 and principal constituents.
