region of New Jersey ; lesser collections have been made in 

 Vermont, eastern Massachusetts and Connecticut. Sufficient 

 time has been spent in these different regions to warrant a 

 rough comparison. The region about New York appears 

 to be by considerable the richest in number of species. The 

 region about Boston possesses a good number of species, but brief 

 visits at different seasons have made it appear doubtful if even a 

 thorough exploration would disclose as great variety as is to be 

 found around New York. Litchfield county, Connecticut, is a 

 disappointing region. The very numerous streams would lead 

 one to expect to find a large number of forms. However, during 

 a trip across the county in September very few Chlorophyceae 

 except Spirogyra and Oedogonium were found ; in the spring 

 months some very interesting forms were collected, but no great 

 number could be obtained. 



In Vermont, from summer explorations in the vicinity of Bur- 

 lington and Grand Isle, and investigations during more than a 

 year at St. Johnsbury, we have been forced to the conclusion 

 that there is no great number of forms of common occurence. 

 Possibly more might be seen in the western part of the state 

 in the spring, but the pools and streams there are much less 

 affected by the summer heat than those about New York, and 

 consequently one would not expect a great difference between 

 the spring and summer algal floras. Indeed, Draparnaldia, 

 which disappears entirely from New York streams during the 

 summer has been found at St. Johnsbury in August, so that 

 a larger number of species of Myxonema also might be expected. 



In the vicinity of New York so many of the streams are nearly 

 or quite exhausted during the summer months that one would 

 not expect at that season to find many of these pure-water loving 

 plants. Nevertheless even during the hottest days in the fountain 

 basins and watering-troughs there is a sufficient abundance of 

 material to keep one busy in collecting and comparing different 

 forms, particularly of Myxonema, and it is hardly to be supposed 

 that the whole number of these summer forms is here treated. 



It is to be regretted that there has been necessity for assuming 

 so critical and perhaps apparently pugnacious an attitude toward 

 the work of others, and in particular Americans, but possibly
