Boulware, JT 1942 38 Itinerary Apr. 3 Mud Creek, 800 ft., 3½ mi. SW San Juan, Monterey Co., Calif. About 11 AM we left Watsonville and drove south over Highway No. 1 to Salinas. Moss Landing was a veritable hive of human activity — a large national defense project apparently in progress. We passed Elkhorn Slough and noticed mud hens and terns. After lunch in Salinas we went to the home of Mr. O. P. Silliman at 225 West Alical Street. Mr. and Mrs. Silliman were most cordial. Mr. Silliman showed us a part of his collection of birds eggs and nests, seemingly a very fine collection. He has many rare books which we did not have time to look at. We looked at a part of his mammal collection, especially his kangaroo rats (Dipodomyx).

Unfortunately, none of the skulls are with these specimens. It seems they are still in the possession of Von Bloeker who is cleaning them. Mr. Silliman was so kind as to lend us a carbon manuscript of Von Bloeker's thesis for the duration of our trip. He also recommended a place where we might camp at the west base of the northern end of the Gabilan Range and led us out there in his car. We proceeded 3 miles north of Salinas on Highway No. 101, turned right on the San Juan Road for about 5 miles, and then right again on the Old San Juan Road for about 3 miles. We are camped near Mud Creek on the
