Introduction
Although very brief, this account is significant in observing surfboard riding at Waikiki and Haleiwa, on the north shore of Oahu.

Josephine E. Tilden (1869-1957)
An American expert on algae, Tilden was the first woman scientist employed by the University of Minnesota.

After spending several summers in work on the coasts of Washington and Vancouver Island, in which region the algal flora is, for the most part, arctic in character, it seemed that a study of tropical marine and fresh water vegetation would be beneficial. Previously no special collecting of this sort had been done in Hawaii, so that the discovery of interesting, rare and new forms might be expected.
Accordingly, a trip to this group of islands was planned.
The party, consisting of my mother, myself and Miss Caroline M. Crosby, left Minneapolis on April 30, 1900, arriving four days later at Vancouver,

Sometimes we would all three of us go off for a stay of several days at a more distant place.
We spent four days at Waikiki beach, where numerous new marine forms were picked up from the "wash."
Both here and at Waianae we had many opportunities of seeing surf-riding, by native men and boys.

The surfboard is shaped like an ironing board, three feet wide and nine feet long.
The man swims out to smooth water, selects a wave of the right kind and mounts his board.
It receives the momentum of the surf and he rides in on the surface of the water and is landed safely on the beach.
Several days were spent at the hotel at Waialua, "by the sea," and, though camping out and roughing it have their charms, we thoroughly enjoyed our stay at this place, Haleiwa, "beautiful home."
