J. Rodger - 1942 Ennerees skiltonianus July 8 (cont) Mrs. Vert Zool, Univ. Calg., Berkeley, Alameda Co., Cal. observe the eggs in place, I would have to devise some sort of contraption that could be opened up. June 20, 22, 23 I made my such a contraption. The following sketch gives a general idea of a unit - for one skink. Five such units were made; 2, 12" x 12"; 2, 8" x 10"; 1, (in around jar) 6" in diam. spaces between units actually narrower than in this sketch - Soil layer on top of each quarter of the unit Nails, by means of which quarters of the unit can be lifted for examination of the soil layers below. 1/8" x 1/2" strip to hold soil on top of bottom board 1/4" to 7/8" layer of light sandy loam [Part of one top quarter cut away to show lower layer of dirt] Units like these were made for the aquaria used before (p.19), two for each, and one for algalor mayonnaise jarcker. The soil on top is occasionally sprinkled with water, taking care not to let much water (or new water) 7/8" board for insulation and to soak up any surplus water that might be poured on top or run down thru hole to allow skink access to soil below
