sented about fifty papers, on food products, water supply, oils, 

 and so on, but notably on foods ; while Professor Sayre, begin- 

 ning with his paper on loco weed in 1886, has presented about 

 the same number, for the most part on the chemistry of drugs, 

 spices, tea and coffee. The work of Professors Failyer and 

 Willard is devoted largely to agricultural chemistry, in which 

 line they have presented many papers. 



In physics and engineering, our Transactions, beginning 

 with the fifth meeting, contain a series of valuable papers by 

 Tweeddale, Nichols, Blake, Smith, Marvin, Hoad, Murphy and 

 many others, on a wide variety of subjects, from the theoreti- 

 cal to the most severely practical. Such titles as the following 

 illustrate the character of this work : 



On Ventilation. Tweeddale, 1872. 



The Water Supply of Kansas. Tweeddale, 1874. 



Statistics on Color-Blindness in the University of Kansas. Nichols, 

 1884. 



Tests of Cement Manufactured in Kansas. Murphy, 1889. 



Magnetic Declination in Kansas. Marvin, 1889. 



Maximum Bending Moments for Moving Loads in a Draw Beam. 

 Murphy, 1892. 



Tests of Strength of Building Stones. Marvin. 1893. 



Collection and Storage of Water in Kansas. Murphy, 1894. 



Water Supply from a Sanitary Standpoint. Marvin, 1901. 



Effect of Clay and Loam on Portland Cement. Hoad, 1904. 



On Improved Water Supply for the City of Emporia. Smith, 1910. 



Finally, in the forty-seven years of its existence the Acad- 

 emy has accumulated a library of at least 6000 bound volumes, 

 and fully as many pamphlets. These represent the work of 

 scientific investigators in all the leading countries, as well as 

 our own, and form a very valuable addition to libraries of the 

 state. This library has been secured almost entirely by ex- 

 change for the Transactions of the Academy. 



I have thus sketched the growth and work of the Academy 

 in an endeavor to emphasize the fact that from the beginning, 

 when the state was new, and when scientific knowledge of its re- 

 sources and of the composition of its plant and animal life was 

 sadly needed, the members have attacked the problems at hand 

 and carried them through the succeeding years, accumulating 

 and recording knowledge of priceless value to the state. Much 

 of the work has been classification — taking an inventory, as it 

 were, but such work is imperative. I have also attempted to 

 show that the Kansas Academy of Science has been the means
