W. Rimer 1950 Journal 19 Mar. Mexico; Durango: streams where cottonwoods a vivid green. Range land and cultivated areas appear everywhere well tended and intelligently managed. 20 Mar. Mexico: Aguascalientes: left our camp west of Durango after taking several scrub jays and a woodpecker and noting a large number of other species. On trip down to Durango stopped few moments at bottom of Rio Chico to look in large stream pool for Dinobystoma larvae in hopes one not taken at El Salto camp could be replaced. No luck!

Points along the way: Nombre de Dios a small town with detour through old cobblestone streets. Appears to be first really unpolluted town. How long will such a condition last?

Mexico: Queretaro: Drove to Drapeato and spent most of afternoon visiting with Mr. Chester Lander and family. Very hospitable.
