vited into this region to spend six weeks of the summer of 1906 

 at the ]\Iarine Biological Station of the University of Washing- 

 ton. The station is located at Friday Harbor, on the Island of 

 San Juan, the largest of the many islands composing the San 

 Juan Archipelago and the County of San Juan, Washington. 

 The region had been sufficiently exploited so that it was known 

 that the opportunity for botanizing was too good to let pass, for 

 here it was that Professor Josephine E. Tilden had stopped 

 years ago, before the Minnesota Seaside Station was established 

 in the Strait of San Juan de Fuca. Also the work of Professor 

 T. C. Ivincaid on the marine animals of tlie archipelago and 

 other portions ()f tlie coast was well known, au<l the opportunity 

 of seeing this expert in the study of marine life at work was an 

 incentive which would have been sufficient to induce any lover (^f 

 out-of-door study to decide to take the long jonrney invohed. 

 Also, the writer had examined lichens collected by members of 

 the party of the Minnesota Seaside Station all the way from 

 Banff, in tlie Canadian Pockies, to the Minnesota Station on Van 

 Couver Island, as well as those collected by Dr. Frye and his stu- 

 dents in the San Juaji Archipelago and other portions of Western 

 Washino-ton, so that the chance of studving this flora at first hand 

 was another strong incentive. Likewise Dr. T^. U. Gardner, Pro- 

 fessor Josephine E. Tilden and Dr. Frye had worked on the 

 marine alga^ sufficiently to enable one not well acquainted with 

 these forms to add considerably to his knowledge of them even 

 in so short a time. Finally, there was the added interest in 

 seeing a seed-plant flora quite different from that east of the 

 Pocky Mountains. 



The history of the early exploration and settlement of the 

 San Juan Archipelago is very interesting, involving the narra- 

 tion of the exploits of Peter Puget, George Vancouver and many 

 other persons, but we nuist pass all this by and confine ourselves 

 mainly to biological considerations. Friday Harbor, the county 

 seat of San Juan County and the seat of the Marine Biological 

 Station of the I^niversitv of Washington, is a village of about
