From 8-year old Hilda’s diary:

This afternoon we went out in a boat with a few other people from the Hotel. Everyone here is supposed to go fishing but Daddy hates fishing, so we just rode in the boat without trying to get any fish. I was glad because I don’t think I would like to catch a fish. Daddy says, “I like my fish on a silver platter with parsley, butter and lemon.” We saw a few big homes on the shore and we went to Emerald Bay and then out to the middle of the Lake. It was beautiful and scary too. You can see to the bottom of the lake and the colors are shades of blue and green and as we went out to the middle it was a beautiful shade of dark blue. Daddy said it was the color of cobalt. I don’t know what that is, but I’ll ask him.
