SCIENCE. 



Til 



J. A. Udden, professor in Augustana College, 

 geologist. 



W. W. Atwood, of the University of Cldoago, 

 geologist. 



Dr. Stuart Weller, of tlie University of Chicago, 

 geologist. 



Mr. Ross C. Purdy, of the State School of 

 Ceramics, ceramist. 



Not all of the men appointed will be able 

 to devote their full time to the survey work, 

 but assurances have been received that all 

 will give some time to it. Professor Rolfe 

 and Mr. Purdy, assisted by Mr. Fox, will de- 

 vote particular attention to the clay resources 

 of the state beginning their work probably 

 with a study of paving brick and the clays 

 used in its manufacture. 



Professor Parr, Mr. Grout, Mr. Van Horn 

 and the director of survey, Mr. Bain, will 

 devote their time largely to a study of the coal 

 fields. It is proposed to take samples of the 

 various seams and to study their qualities as 

 well as their distribution in the field. In the 

 latter work Dr. "Weller and Mr. Atwood will 



Professor Udden will devote his time to a 

 study of the underground waters of the state 

 with a view to the determination of the limits 

 of the various artesian basins and the depth to 

 which it is necessary to go to obtain good 

 water for municipal and other purposes. In 

 this work he will be assisted by Dr. Bartow 

 and the State "Water Survey, which will make 

 the necessary analyses and laboratory tests. 



Dr. Grant, with such assistance as may be 

 necessary, will take up the study of the lead 

 and zinc fields found near Galena continuing 

 the work done by the state of Wisconsin. 



Professor Salisbury, assisted by various 

 others yet to be appointed, will prepare a series 

 of bulletins for use in the schools, descriptive 

 of the geography and the geology of impor- 

 tant type localities within the state. So far 

 arrangements have been made for such bul- 

 letins covering the lake shore from Evanston 

 north, the Illinois Valley near Peoria, and 

 the Mississippi Valley between Savanna and 

 Eock Island, and at East St. Louis. The first 

 of these bulletins is now being prepared by 

 Mr. Goldthwaite, of Northwestern University, 

 and Mr. Atwood, of Chicago. 



THE MEMORIAL OF MAJOR WALTER REED, 



U. S. A. 



The executive committee of the Walter 

 Reed Memorial Association, consisting of 

 Daniel C. Gilman, George M. Sternberg,. 

 Chas. J. Bell, A. F. A. King, J. R. Kean, 

 W. D. McCaw and Calvin DeWitt, has issued, 

 under date of February 1, the following letter : 



You are doubtless aware that to Major Walter 

 Reed, surgeon U. S. Army, is due, in a very large 

 degree, the demonstration that yellow fever is 

 propagated by a mosquito. By this demonstration 

 the spread of the pestilence has been averted, and, 

 when proper precautions are taken, the danger is 

 almost annihilated. The immense benefits which 

 have come to humanity from this discovery can 

 hardly be estimated. 



Under these circumstances, a general desire has. 

 been shown to honor this great benefactor, and 

 likewise give to his widow some recognition of his 

 service to mankind. An incorporation has been 

 formed in Washington which is endeavoring to 

 raise a fund of $25,000, the income to be paid to 

 his widow and the principal to be reserved for a 

 permanent memorial in the city of Washington. 

 The amount now subscribed is somewhat over 

 $16,000; by far the largest number of contribu- 

 tors are of the medical profession. There is 

 one subscription of $2,000, two of $1,000, two 

 of $2.50, several of $100, and many of less amount. 

 The association in charge of this movement con- 

 siders that the time has now come to appeal to 

 a wider circle than has yet been reached and to 

 ask their subscriptions. 



Your support is respectfully solicited, and any 

 amount that you may be disposed to contribute 

 may be sent to the American .Security and Trust 

 Company of Washington, D. C, the president of 

 which, Mr. Charles J. Bell, is treasurer of the 

 fund. To complete the fund and cover incidental 

 expenses, including a marble bust of Major Reed, 

 $10,000 is needed. The desire of the committee 

 is to close the subscription before the end of this 

 month. Communications should be addressed to 

 the secretary at No. 1707 21st Street, N. W., 

 Washington, D. C.
