W. Riemer 1949 Journal 7 Aug. New Mexico, Chaves Co., Roswell to Eddy Co., Carlsbad compactilis and seen was a Natrix (?) in the river. Found that by hitting or tapping two loosely held rocks together a good imitation of Acris could be made. Succeeding in getting the chorus to respond several times with such a method. First calls made singly and slowly tempo built up as in a train starting to roll. No notes as to timing and pitch taken. 8 Aug. New Mexico, Eddy Co., Carlsbad Caverns Nat'l Park Morning spent doing laundry for first time since Yuma. In afternoon drove S to Parks area and inspected the "hole in the ground." Caverns not seen since no more trips scheduled for that day. Returning to entrance near White's City spent about hour looking for Sceloporus poinsettii in rocky outcrops in canyon next S of entrance road. No Sceloporus seen but Urosaurus and Holbrookia texana taken. Discovered Coluber brevis under rock slabs and collected three. All young. Afternoon warm but heavily overcast. Returned to Carlsbad to 2 camp for night.
