island's northwest side. He also stated thai pebbles often are found 
at exceptional hights on the hills because the farmers use sand with 
sonie contained gravel for bedding in then-stables and consequent!) 
scatter it over their fields at all altitudes. 
Prof. Shaler also cited the custom among the [ndians of cooking 
wllM heated boulders, and as the local limestones and sandstones were 
" f " ,ln v;ilui ' for this purpose they often brought granitic boulders from 
;| distance. In answer to these suggestions, Prof. Wright cited 
boulders of two tons' weight, which manifestly could not be explained 
in such ways. 
Prof. Angelo Heilprin then mentioned .certain polished and grooved 
rocks of South Africa which had been regarded as glaciated. Investi- 
gation, however, has shown that the polishing is due to the habit of 
elephants, formerly abundant there, to resort to them and roll and 
scrape on them, and that the grooves are due to the rubbing of their 
I usks.* 
Mr. Leverett corroborated the observations of Prof. Wright in the 
northern pari of the area. 
Four great Kame Aims of western New York. H. I,. Fairchild, 
Rochester, \. V. This paper, read onlj in abstract, described four 
massive deposits of waterlaid drift, of mound and basin topography, 
with peculiar features of altitude and relation. One of the areas lies 
south of Sodus bay, between Lyons and Geneva, and is called the 
Junius area. It is some miles' in extent, holding several small lakes, 
and forms the highest ground upon the meridian between lake Ontario 
and the Devonian plateau enclosing the " Finger lakes.** The three 
other areas are south of Irondequoil bay. One occupies the valley of 
the Erondequoit creek, and lies partly below the level of the glacial lake 
Eroquois. Another is the Mendon area, which, with the Erondequoit 
area, was mentioned in the American Geologist for last July (vol. 
xvi, pp. 111. 50). i .asily, the Victor ana lies contiguous to the Eronde 
quoit, southward, and is the most massive and elevated of them all. 
rising to 1,1 on feet above the sea, and being the highest point in western 
New fork north of the Devonian plateau. 
Erosion planes of the glacial lake Warren are evident upon these 
areas, the upper one being considerably under 900 feet. 
The paper described these very massive kame deposits in detail, with 
maps and photographs, and discussed the problems of their formation 
ami of the upward transportation of boulders and smaller cobbles and 
pebbles to hio-|,t s some hundreds of feet above their parenl ledges not 
many miles distant. |It is to be published in the next number of the 
Journal of Geology. | 
♦Similarly, in western Minnesota and northwestward, boulders are 
often found having their edges and corners smoothly polished by the 
rubbing of buffaloes, which twenty to fifty years ago roamed there in 
countless herds, but now are almost exterminated. (Geology of Min- 
nesota, Vol. ll. 1SSS. p. olC.i
