At present the buildings of the Station number two and comprise a small house, 25 by 12 feet, on the shore, with a larger building, 60 by 25 feet, in the rear and on the higher ground. A third building is to be erected during the winter. Last summer, when a party of thirty-three went west from Minneapolis, it was apparent that the buildings would be inconveniently crowded, but by devoting half of the large living room to laboratory purposes it was possible to accommodate all who desired to work. The small house was used principally for microscopic work and for preservation of anatomical material. It received the name of the 'Formalose Club' from some ingenious members of the party. The large house is two stories in height and arranged for general camp purposes. Below, a transverse hallway divides the kitchen and storeroom from the

dining and living room. The latter with its large fireplace at the end and its festoons of flags and bunting in the University colors proved to be attractive and cheerful. Above, two large bunk rooms, one for men and one for women, afford the comforts of balsam beds to the weary, after the day's work is done.

Station equipment did not present a very serious problem during the first season. Most of the party preferred to devote their energies to the collection of material. However, some twelve or fifteen microscopes were in use, and both the small library and the store of chemicals and glassware were daily drawn upon.

In view of the many novel varieties and curious habits of the seaweeds they were the principal objects of study during the season of 1901.

Not only did they prove of unusual taxonomic interest-some entirely new species being collected-but also well worthy of careful ecological research. Their zonal distribution, formation groups and choice of special substrata were noted, together with their behavior at different stages of the tide. Often very sharp lines of demarcation between different algal societies were exhibited. In Figure 8 an excellent example is reproduced. At the rear, near the center, is seen the characteristic fringe of salal (Gaultheria shallon) in front of which Enteromorpha colonies are established upon the flat sandstone. In the foreground appears a sharp zone of wrack (Fucus evanescens). In this view there is also shown some of the unusually vigoros epiphytic moss-vegetation so

abundantly represented on Vancouver island. Another very distinct instance of zonal distribution is shown in Figure 9, the photograph having been taken at low tide. In the foreground the slender leaves of a marine angiosperm (Phyllospadix scouleri) are seen, spread over which are fronds of Egregia, one of the most notable of the west coast kelps. The sides of the dome-shaped rock are draped with kelp, principally Egregia and Alaria, while the top is covered with a fairly uniform and copious growth of the alga which has passed under the name of Halosaccion hydrophora, but concerning which it is possible that an error has been made by American phycologists.

Under other topographic conditions the zonal distribution is not so

evident, and in Figure 10 is shown an arrangement of algae and animals upon a much creviced slate. Barnacles of two distinct types and mussels, mingled with a growth of Endocladia muricata, appear in this

view, but the general grouping is less clearly concentric. Nevertheless the Endocladia zone is pretty well defined as a mid-tide algal society and sometimes shows sharp demarcation when favorably situated for a pure growth.

Among the high-tide.algae-those occupying the upper zones-Peletia is an interesting form. It occurs at the same levels adopted by

Fucus, of which it is taxonomically an ally, and often produces considerable beds, though not everywhere abundant like the Fucus.

Figure 11 a group of Pelvetia is shown and its habit can easily be recognized.

Of the low-tide algae there is not only a characteristic segregation relative to depth of water, but a careful selection of habits more or less exposed to the influence of the surf and surge. Quite a characteristic group of surf-plants including such kelps as Postelsia palmaeformis and one species of Alaria display themselves where the surf is strongest and seem to require the foaming water of the breakers for their best development. Below these in more sheltered places

one finds Hedophyllum, Alaria and Egregia. Below Postelsia, but exposed to strong surge, grow the Lessonias, while Pterygophora seeks the

bottom of the surge and Nereocystis anchors itself in still deeper water outside the line of breakers. In this outer zone, too, Macrocystis and Dictyoneuron seem to find their best opportunities for growth, while Costaria comes somewhat nearer shore. The latter is, however, commonly brought up with the Nereocystis holdfasts, when they are detached from the bottom. Figure 13 shows the exposure of surgeplants at low tide. On the right is Lessonia littoralis. In front is Laminaria bongardiana and on the left is Phyllospadix scouleri. The Lessonia, in particular, is TAKEN FROM THE WASH AND PHOTOGRAPHED beautifully adapted by its massive trunk and slender leaves to maintain its foothold in the surge and with Postelsia in the surf and Nereocystis in the deeper water shows in magnificent fashion the work
