aperture provided for that purpose near the periphery of the outer disc so that by 

 inserting a pin through corresponding apertures in each disc and above the lower 

 line of the belt, the same may be coiled by hand upon the hub of the device and 

 thereby be protected from the weather, and at the same time be easy of access 

 when occasion requires. 



The driving-pulley of the machine is placed somewhat above the plane of 

 the guiding-pulley so that both lines of the belt will be situated above the guiding- 

 pulley journal. But it is not necessary, however, that both lines of belt should 

 run within the diameter of the discs; on the contrary it is preferable that the upper 

 line operate entirely above the guiding-pulley. This invention was recently 

 patented by Mr. F. B. Ray, of Kansas City, Mo. 



EDITORIAL NOTES. 



Through the courtesy of Mr. J. S. Chase 

 of this city, now visiting in Dakota Terri- 

 tory, we have received a photographic re- 

 presentation of a tornado-cloud taken by 

 Mr. F. N. Eobinson, of Howard, Miner Co., 

 D. T, August 28, 1884. The storm passed 

 twenty-two miles west of that place at 4 P. 

 M., moving in a southeasterly direction and 

 remaining in sight more than two hours. It 

 was very destructive, killing several people 

 and destroying all property lying in its 

 track. As a work of art this photograph is 

 admirable, since the details of shape of the 

 funnel and the light and dark shades of the 

 cloud are as distinctly brought out as though 

 the object had been a fixed one in the oper- 

 ator's room ; while as an object of interest 

 and information to the meteorologist noth- 

 ing so satisfactory has ever come within our 

 notice. We consider that Mr. Eobinson is 

 entitled to the thanks of all scientific men 

 for his enterprise in this matter. 



The Fish Commission of Missouri has just 

 published a small book of sixty-four pages, 

 on Carp Culture, with an appendix of Na- 

 tive fish. It will be sent to residents of Mis- 

 souri, free of charge, on 'epplication and en- 

 closure of three cents in postage stamps. Ap- 

 ply to Phil. Ropplin, Jr., Forest Park, St. 

 Louis. 



Prof. A. S. Gatschet, the noted anthro- 

 pologist of the Smithsonian Institution pass- 

 ed through this city on the 21st of August 

 on his way to New Mexico and Colorado. It 

 is a matter of real regret that we were out 

 of town when he called at the office of the 

 Eeview.
