Selecting 27 trees in one block, 6 dead-fall mouse trapswere set under each tree. Traps were set in as many different places onthe trails as was possible. Some were on the underground trails, someat windfall fruit, some on the surface trails, etc. Each trap site wasnumbered and marked. The traps were run as often as was necessary totrap out all the mice present. A complete record was taken of all thatwere caught. Records were kept of the following: Date and time the traps wereset and re-run; species caught; weight, sex and measurements of allmice; type of orchard floor cover; weather conditions; location of alltraps in area; stomach contents of all pine mice; location of trail systems,nests and food caches.

It willbe added to and correlated with the data collected by other men in thisregion. Our observations to date show that: 1. Pine and meadow mice were caught in the same surface trails. 2. Pine mice were caught as often on the surface trails as in theirunderground burrows. 3. In surface trails the meadow mice were usually caught first,followed by the pine mice. 4. The underground burrows of the pine mouse and the surfacerunways of the meadow mouse were one continuous system. 5. Burrows of the pine mouse, as a rule, came to the surface at apoint near the extremities of the tree branches. 6. During this time (October) the pine mice were very active storin
