the Waters of the Springs and Torrents, 

 which the Froft fixeth. This is fo true, that 

 when there is much Snow in Winter, the 

 Waters are very high the enfuing Summer. 

 But when great Rains chance to f^Yi mJanu^ 

 ary^ then the Snow, not yet being well hard- 

 ned, melteth on a fadden altogether. And 

 when this melting is not fo violent, all the 

 Snow that will melt, melts at the end of 

 May or at the beginning of Jum ; fo that, 

 there remaining but the ftock of Ice for en- 

 tertaining the Increafe of the Water unto 

 the Month of Augvfi^ forne have thence 

 been induced to fay, that this Increafe, which 

 amounts, as has been faid, to 15 Feet Wa^ 

 ter generally all over the Lake, is caufed by 

 the Herbs, growing, as they pretend, at its 

 bottom in great abundance ; and that thefe 

 Herbs, whilft growing, do force the Water 

 upwards, and dying in Autumn make the 

 Water to fink lower. Which h not fatisfac- 

 tory to me, becaufe there are no Herbs feen 

 upon the Lake, and very little within it, and 

 the Banks being very dry. 



Others there are, that will have this Wa- 

 ter rarified by the Heat of the Sun, and 

 thereupon flvelFd on the Borders, hot Wa- 

 ter not being fo high in the middle as cold. 



This is certain, that all the Rivers and 

 Torrents, that fall into this Lake, carry 

 with them ftore of Stones and Earth, which 

 may indeed enlarge and raife it : But fuch an 

 aurmentation or rife cannot be fenfible but 

 from Age to Age ^ not to mention, that in 

 Winter, whilft the Water is low, the Stones 

 of the Lakes are carried away for building ov 

 fbrtifying at Cmm, 4|
