Memorial of Ulysses Orange Cox. 47 
United States Fish Commission in connection with the exploration of rivers 
and lakes. He built and equipped the house-boat “Megalops” with which he 
made a trip down the Mississippi River for the Minnesota Geological and 
Natural History Survey. In 1898 he was with the writer on an investiga- 
tion of the streams of Nebraska, South Dakota, and Wyoming for the United 
States Fish Commission. In 1896 he studied Lake Pend d’Oreille and cer- 
tin streams in the State of Washington. and in August of that year he and 
I went with the Mazamas (a club of mountain climbers, chiefly of Port- 
land, Oregon) to Crater Lake, Oregon, where we made certain investiga- 
tions for the U. 8S. Fish Commission. These investigations included the 
making of several soundings and the taking of serial temperatures at 100- 
foot intervals from surface to bottom of the 2,000 feet of depth of that 
very wonderful lake. 
Another investigation he made for the U. S. Bureau of Fisheries was a 
study of the freshwater mussels (Unionidze) of the lower Wabash River. 
In a small launch, towing a barge on which to carry their collections, he 
and our good mutual friend, the late Dr. J. T. Scovell, examined the Wabash 
critically from Terre Haute to Vincennes, with special reference to that 
species of mussel known as the ‘“‘mucket” (Lampsilis ligamentinus), which 
is one of the best in pearl button making. Just at that time Professors 
George Lefevre and W. ©. Curtis of the University of Missouri were carry- 
ing on their brilliant investigations on the artificial inoculation of fishes 
with the glochidia of Unionidse. They desired a large number of fine muck- 
ets. and Professor Cox was able to supply them with abundant and excel- 
lent specimens from the Wabash. In a letter to Professor Cox, Dr. Lefevre 
wrote: 
“T want to thank you for your kind assistance in securing for our 
recent experiments at La Crosse such a fine lot of muckets and yel- 
low backs. They were received in excellent condition and furnished 
us with an abundant supply of glochidia for the infection of the fish. 
Twenty-two of the muckets contained ripe glochidia and fifteen of the 
yellowbacks, yielding altogether a sufficient quantity for the infection 
of nearly the entire lot of fish which we had on hand, namely, about 
25,000. 
“There was no indication that the muckets were not at the height 
of the breeding season, as the pouches were gorged with glochidia in 
every specimen containing them, but the yellowbacks appeared to be 
on the decline, as we found quite a number of completely spent fe- 
males. The experiments were highly successful in every way, and 
we are greatly indebted to all who contributed their assistance to the 
work.” 
Soon after his election as head of the department of Biology in the Indi- 
ana State Normal School, the State Legislature provided for the teaching 
of agriculture in the public schools. Provision for instruction in that 
subject in the Normal was at once made, and Professor Cox was placed 
in charge. This was in addition to his other numerous duties. The rooms 
in the basement, then occupied by the department of Biology, were soon 
outgrown and, largely through the efforts of Professor Cox, a new Science 
Hall, adequate in its appointments and architecturally beautiful, was soon
