concentration. ‘These are perhaps summarized best in his address 
as retiring president of the American Association for the Advance- 
ment of Science, delivered at Denver in toot. 
With his acceptance of the presidency of the University of 
Wisconsin, Dr. Van Hise made a serious and at first confident 
effort to continue his geological researches in addition to his admin- 
istrative duties, but he soon became so deeply engrossed in the 
humanistic phases of his new work that there was little time left 
for effective research in the old lines, and so his foremost interest 
shifted to the new work. The two interests, however, merged, in 
a measure, in his study of the application of natural resources to 
the general welfare of man, especially the conservation of natural 
resources, to which he made several notable Comlualourcrens, among 
them the best book on the subject. 
It was natural to pass from this special line of economic study 
to the broader aspects of current commercial and industrial ques- 
tions, where his chief interest seems soon to have centered on the 
organization and co-ordination of effort as the key to the solution 
of the vexed questions that agitate this field. Most notable among 
his writings In this line perhaps is his book Concentration and Con- 
trol, a Solution of the Trust Problem in the United Staies. 
The utter breakdown of the basis on which the leading-industrial 
legislation of the United States had been based, as soon as the stress 
of the Great War forced the nation itself to become a vast industrial 
institution, and the precipitate resort of the nation to practices 
diametrically opposed to those embodied in its previous legislation, 
deeply interested President Van Hise and obviously rendered his 
previous views on co-operation and co-ordination still more definite 
and strong. At any rate, these views were urged with still more 
vigor in his last years and formed the keynote of his book Con- 
servation and Regulation in the United States during the War. 
President Van Hise was profoundly interested in the war and 
made its probable intellectual, ethical, and economic outcome a 
special subject of study. As an administrator he vigorously 
marshaled the resources of the institution over which he presided 
in support of a strenuous prosecution of the war, while personally 
he contributed directly to it by lectures, papers, and other service
