In pointing out recently what the writer believes to be 

 the true origin of perhaps the majorit}' of the lower Silurian 

 fossils found along the lake shore near Winona last June, we 

 probably left an important matter too slightly alluded to, if 

 not unrecorded, viz : The numerous Archaean glaciated 

 pebbles or shingle frequently observed there. Assuredly 

 such could not have been derived from any place but the far 

 North. This occurrence was clearly traced to the glacial 

 clay cliffs along the shore, mingled with others containing 

 similar lower Silurian organisms, as the hammer reveals on 

 breaking up the shore shingle. Can local " field Geology " 

 satisfactorily account for the presence of either? No. We 

 must look far beyond the neighborhood of the lake itself for 

 the solution of the difiiculty. Here I may be permitted to 

 remind a reader unacquainted with Geological terms that 

 scientific men use the word rock for even a soft sedimentary 

 deposit as qmx glacial clay beds. It may be necessarj^ to direct 

 attention to the circumstance, otherwise drift specimens may 

 be excluded from local lists,

The city quarry, at the head of the Strongman Road, 

 presented so few specimens since its opening that the writer 

 concluded not to waste much time there on the mere chance 

 of finding a few new Graptolites, Yet a brief visit was paid 

 almost daily during the working season, on the way to other 

 localities which furnished Sponges and Bryozoons, In a
