remarked on the preceding ctalogues of the local flora, including 

 the list prepared by Dr. Torrey, Dr. Eddy, and Mr. Knevals, 

 published by the Lyceum of Natural History in 1819, the list 

 prepared by Mr. Leggett and his associates, published in Volumes 

 1-6 of Bulletin, 1 870-1 876, and the catalogue of 1888, prepared 

 by himself with the aid of Mr. Stearns and Mr. Poggenburg. 

 Mr. Taylor's work is much more elaborate than any of the pre- 

 ceding catalogues, as it contains keys for the rapid determination 

 of species, detailed citations of distribution, and of habitat, 

 together with statements of distribution by geological formations, 

 by altitude, and with relation to temperature and the length of 

 the growing season. 



Mr. Otto Kunkel spoke of collecting rusts in the Adirondacks. 

 Dr. R. M. Harper gave a brief description of certain floral 

 features of northern Michigan. An abstract follows: 



The biological station of the University of Michigan is located 

 in the wilderness on the shore of Douglas Lake, about 17 miles 

 south of the Straits of Mackinac. The lake covers seven square 

 miles, and has a varied and interesting flora along its shores. 

 The surrounding country is very sandy, and was originally 

 covered mostly with white pine forests, which were cut off about 

 thirty years ago, and have not reproduced themselves to any 

 considerable extent since, on account of too frequent fires. 

 There are small areas of hardwood forest, in nearly primeval 

 condition, and many swamps full of conifers of the traditional or 

 conventional narrow conical form, familiar in all parts of the 

 northern hemisphere where the snowfall is heavy. The abun- 

 dance of fleshy fruits in that neighborhood, which is near the 

 southern edge of the boreal conifer region, is noteworthy. They 

 occur in many different families, even including the Cyperaceae. 



Adjournment followed.
