ridges, sometimes two or three feet high. Tliese ridges or ice beaches 

 are generally washed a^Aay by the high water common in spring, but 

 sometimes they remain, making a distinct and somewhat peculiar plant 

 region. Along the steep banks, the boulders that have fallen to the beach 

 during the summer are crowded against the bank by the ice, making 

 in some places quite extensive stone walls. With such a variety of soils 

 as occur in and about Lake Maxinkuckee, a varied flora may be expected. 

 In the waters of the lake there are great quantities of microscopic life, 

 called plankton. Of the microscopic plants, protococcus, rivularia, oscil- 

 laria, diatoms, desmids and others are common everywhere in the open 

 lake, but were most abundant among the higher vegetation along the 

 shores. Occasionally rivularia would occur in such quantities as to be 

 conspicuous to the naked eye. Spirogyra, vaucheria, oedogonium, hydro- 

 diction, stigeoclouium, nostoc, cladophera, zygnema, chetophora, and 

 others often occurred in masses in the shallow water. Chara and nitella 

 were very abundant. 



Nitella sp? A tall, slender plant, was abundant between 18 and 22 feet, 

 ranging from 12 to 25 feet. In water from 20 to 25 feet deep we 

 seldom found anything beside niteUa. 

 Nitella sp? A small, delicate plant found in shallow water, common in 



the marshes and in the lake out to a depth of two feet. 

 Chara sp? A slender, rank-growing plant quite free from lime. Was 

 abundant between 10 and 14 feet, ranging from eight to 24 feet. In 

 some localities this chara was the only plant found between 10 and 14 

 feet. 

 Chara sp? A stout plant, seldom more than eight inches high, was 

 thickly coated with lime. It was most abundant at a depth of from 

 eight to 10 feet, often forming a thick mat of vegetation to the exclu- 

 sion of other plants. 

 Chara sp? Much smaller than the above mentioned, quite abundant in 

 shallow water, often the only vegetation. It was usually thickly 

 coated with lime. 



There are doubtless other species of chara and nitella about the 

 lake, but the ones mentoned are the most abundant. 

 Potamogeton natans L. This plant was more common in the southwestern 



portion of the lake, growing in water from four to six feet deep.
