THE H-H WATERWHEEL AND PUMP FOR FARM 

 WATERWORKS 



T. P. HICKERSON 



The Hutchison-Hickerson Waterwheel and Pump, recently in- 

 vented by R. B. Hutchison of Wilkinsburg, Pa., and T. F. Hickerson 

 of Chapel Hill, N. C, is a discovery of a new application of the 

 old principle of the overshot wheel in the design of a small easy run- 

 ning combination Wheel and Pump and Stand (made in the factory 

 complete for installation) to utilize the flow and fall of small brooks 

 as power for operating continuously a pump which pushes pure spring 

 water to higher elevations. 



The remarkable simplicity, adaptability, and reliability of this 

 machine brings it in direct competition with Hydraulic Rams, all of 

 whose defects seem to be met satisfactorily by the Wheel and Pump. 



One dozen of these Wheels and Pumps have been introduced in 

 North Carolina during the past year. Among these is one which de- 

 livers every day through a vertical height of 45 feet 500 gallons of 

 spring water for a large farm home, where the power of the stream 

 •which operates the wheel is only 1-100 of a horse power. 



ON LEIDY'S OURAMOEBA AND ITS OCCURRENCE AT 

 GREENSBORO, N. C. 



E. W. GUDGER 



In the fall of 1914, considerable numbers of large and active 

 Ouramcebas were found at Greensboro. The Amoebas themselves and 

 the locality in which they were found were described. Their activities 

 both in feeding and moving were discussed, and it was noted that there 

 was no reversal of polarity, the tail-feather-like mass of fungous 

 hyphae always remaining posterior. The history of this interesting 

 organism was then reviewed, and the conclusion arrived at that 

 Ouramoeba (tailed Amoeba) is nothing but an ordinary Amoeba which 

 has ingested fungous spores which have germinated and formed a 

 mass of mould hyphae which projects from the posterior end of the 

 animal. The full paper will be published shortly. 



SOME IGNEOUS ROCKS OF MOUNT COLLIER 



JOHN E. SMITH 



Mount Collier is in Orange County, N. C. ; about 5 miles west of 

 Chapel Hill. It is typical of those igneous monadnocks of the eastern 

 Piedmont, most of which rise to a common level about 200 feet above 

 the peneplain. It was formerly much higher and of greater extent 

 this is shown by the position of parts of the mountain that have been
