August 15-1918, Thursday, Port-au-Choix. It rained hard in the early part of the night and the morning has a very thick fog. However we go out at 8.30 A.M. to study the northern peninsula north of Port au Choix. Shortly after we started the sun lifted the fog and the day remained sunny and fine. We crossed over the narrow neck of land between Old Por tau Choix and the outer a French Port au Choix and then walked along the same southward to the point and around it south- ward to the head of Port au Choix Bay to where our camp is situated. We began collecting in the upper part of Richardsons Divi- sion H and near the center of the thickness found it more frutiferous than Dad criticized in 1910. In place fungi are very common but it is very seldom that one gets a good me. The height in considerable material that will help to identify the species. At the northern point of the peninsula the section descend into Division G but on going southward into the bay Port au Choix Bay the strata again rise to about the level seen in the morning = H. In 1910 I noted that Division F on the lower Beaumanoir is present at the north end of the peninsula but I now see that that is a mistake. The peninsula has only Divisions G and H. Division F should come in at the mainland north of this peninsula and toward Beustands Cove.
