NOTES ON THE LATE COLLECTING SEASON 



WINONA AND GRIMSBY. 



The first thing I noticed at tlie foniier place on arrival 

 there for the summer collecting tour, while standing on the 

 high baiik above the lake, was that the ^vater appeared to be 

 very low for the time of my arrival ; that a large tree had 

 been vs'iished ashore and embedded in th.e sand ; that 

 another one in front of A. Wilson's had toppled over and 

 was partly submerged in the lake since last summer, while 

 a third orie, lying a little to the vvest tlien, had disappeared 

 altogether. On proceeding down the slip adjacent, I 

 ascertained a considerable amount of sand had collected 

 about the two former, and the latter liad not actual!}^ dis- 

 appeared as I imagined, but Vv'as merel}^ hidden by the 

 accumulated material v/hich had gathered there. This was 

 removed by tlie water of the lake in rough weather a few 

 days subsequently, ai^d it was found a little to the w^est of 

 the Park that tlie lake level appeared higher, if anything, 

 than in former times. 



Only when tlie water was perfectly calm could I obtain 

 a few specimens (dry shod) from the low^ glacial clay cliffs 

 near the ravine to the west of the camp. The majority 

 were regular not polished or striated. Onh^ in a few' cases 

 they held common Hudson. River fossils, and the embedded 

 shingle appeared to be far less numerous than in former 

 years in the glacial claj' cliffs. 



The way iri wliicli the sand, gravel, etc., collects in 

 places along the sliore differs considerably, and is often 

 calculated to mislead one regarding the lake level. Less 

 than two miles to the east of the camp is a pond which 

 four years ago was fed by a stream from the lake eight 

 inches deep. I^ast year it disappeared altogetlier, giving 

 the localit}' the appearance of a recession of water level at 

 a short distan.ce. Such is not the case, for not many yards 

 to the west, even when the lake was perfectly calm, I 

 noticed last June how rapidly the waters were encroaching
