On 27 June, Assistant Curator Reeds left New York for 



field work in the Arbuckle Mountains of Oklahoma in coopera-

homa. He spent most of the months of July, 



y August and September on this work, returning 



to the Museum on 24 September. Profiles were run, topo- 

 graphic data were assembled, photographs were taken and 

 rocks and fossils were collected, thus supplementing work pre- 

 viously done by him in that region and probably completing the 

 field work required for the monograph on the Hunton forma- 

 tion upon which he has been at work for some years. A 

 large amount of material was collected and shipped to the 

 Museum and a considerable series of rocks and soil samples 

 was collected for the Oklahoma Survey. The first series of 

 fossils, including all the types which may be made as the result 

 of this expedition, will be the property of the Museum, and a 

 set of duplicates will be sent to the State Geological Survey of 

 Oklahoma. 



In September, Mr. W. B. Peters of the Department of 



Preparation and Mr. P. B. Hill spent about three weeks at 



, Weyer's Cave, Virginia, collecting additional mate- 



v rial for the large reproduction of a grotto from 



that cave which is being installed at the north end 



of the Hall of Geology, beside the Copper Queen Cave. 



The great Copper Queen Mine Model, the gift to the 

 Museum of Dr. James Douglas, was opened privately to 



_ _ invited guests on the afternoon of 16 Feb- 



Copper Queen & , . . _ .

Mining Engineers on the evening of 17 Feb- 

 ruary in connection with the annual meeting of the organiza- 

 tion. The model was opened to the public on 18 February. 

 The exhibit includes, besides the large model, a smaller model 

 on the scale of six feet to the inch illustrating one method of 

 mining out a stope and hoisting the ore to the surface. This 

 is a working model, so-called, to the extent that the cages in 

 the shaft go up and down, operated by an automatic electric 

 motor. An attractive feature of the exhibit is the series of 

 magnificent specimens of malachite and azurite from the 

 original Copper Queen Mine which the Museum was fortu-
