27. Mar. 24. San Antonio, Bexar Co., Texas. I arrived here at 11:00 pm last night after a round trip flight to San Diego, California. On the return trip in western Texas, particularly east of the Pecos River, there was a great deal of dust in the air so that the ground objects were not distinct from ±5000 feet above the ground. At the surface level at Midland, visibility was clear for several miles. Today I purchased some maps from the M.L. Ferguson Map Co., San Antonio and departed from that city about 1:30 pm after having lunch with an old friend, Fred W Knight, of that city. I drove to Somerset, Bexar County to contact Mr. G.J. Kim but was informed of his death in October, 1950. The countryside N of Somerset was cultivated or cleared for the most part but there were stands of mesquite here and there. There were some larger trees along the creeks and a more dense growth there also, i.e.: small but more fully-leaved deciduous trees in contrast to mesquite brush of the upland. Live Oak Creek, 2½ mi NE Somerset, Bexar Co., Texas—vegetation as above—pair of Carolina Chickadees and a Black-capped Tanager seen. Further N, along Medina Creek at [illegible], crossing of Somerset Road, trees are taller, no underbrush. I drove S on US 181 after 3:00. Around Berg’s Mill in Bexar Co., there were some large trees in the uplands, deciduous oaks and perhaps other trees as well. 11 mi SE Berg’s Mill, rolling country for about 10 mi farther SE with sand dunes or at least sandy soil. This substrate supported a forest of mixed oak trees, live & deciduous. Otherwise or elsewhere mesquite was extensive.
