MUSEUM NOTES lol 



Ix the aiulitoriuin of the Museuin on the evening of Mareh 28, Captain 

 Frank E. Kleinschinidt, who has reeently returned from a five months' 

 cruise along the coasts of Sil)eria and AUiska, showed a series of moving 

 pictures which gave a reahstic idea of polar bears, moose, mountain sheep, 

 walrus, and seals. 



The ten-ton block of (Jrenville (pre-Cambrian) marble containing a 

 glacial pot hole, which was secured in the town of Russell, St. Lawrence 

 County, New York, has been placed in its permanent position at the east 

 side of the archway in front of the Museum. The block was cut from the 

 surrounding marble by the Gouverneur Marble Company and in January 

 when the roads were frozen, was taken to the nearest railway station, 

 loaded onto a flat car and brought to New York where a heavy six-horse 

 truck transferred it to its new al)iding place at the entrance to the Museum. 

 The pot hole is two feet in diameter and four feet deep, carved by the 

 swirling waters of some sub-glacial stream during the Great Ice Age, boulders, 

 pebbles and gravel having been the grinding tools. 



A LARGE slab showing glacial grooves has been mounted opposite the 

 glacial pot hole under the archway in front of the Museum. The grooves 

 were made during the Great Ice Age by the action of gravel and pebbles 

 under the glacier that covered northeastern North America. The rock 

 is of Devonian Age, came from Kelleys Island and was a gift to the 

 Museum in 1909 by Dr. Charles E. Slocum of Toledo, Ohio. 



The Colombiax expedition has sent to tiae Museum a collection of 

 foiu" lumdred mammals and two thousand birds. These were collected 

 chiefiy on the Quindio trail of the Central Andes, and include specimens 

 from the base tropical zone up to the limit of snow. The specimens from 

 the paramo, that mountain zone lying between the upper limit of trees 

 and the lower limit of snow (12,")()0 to \r)J){)0 feet), contain many species 

 not before represented in the Museum. The collection as a whole adds 

 greatly to the value of ])receding Colombian collections in the light thrown 

 on distribution as afi'ected by altitude and climatic conditions. The 

 combined collections now give sufficient data on which to base a preliminary 

 life-zone map of western Colombia. The expedition on Fel)ruary 14 

 abandoned Cali, which has been the base for the past year, and started for 

 Popayan en route to the headwaters of the Magdalena \'alley, which will 

 serve as a base for future operations. 



A CAST of the (Jangetic dolphin has been added to the exhibition of 

 marine mammals on the third floor. This dolphin of India has never been 

 found far out at sea, but is restricted to rivers, making seasonal migrations 

 from the deep waters where the rivers empty into the sea to the shallows 

 far up among the hills. The cast is a replica of an original mount in the 

 Natural History Museum at Calcutta.
