juncture the Hon. Charles H. Morrill, of 

 Lincoln, came forward with liberal contri- 

 butions for the prosecution and continuance 

 of the work. Then followed during June, 

 July and August of the same year the first of 

 what has become the annual Morrill Geo- 

 logical Expeditions. 



A well equipped party of six (exclusive 

 of guide) namely : T. H. Marsland, F. C. 

 Kenyon, A. C. Morrill, H. H. Everett, J. 

 H. Haines and Erwin H. Barbour in charge, 

 visited the Bad Lands of the State, and es- 

 pecially the Dsemonelix beds, continuing 

 thence into South Dakota and to the Dino- 

 saur beds of Wyoming. 



In 1893 a similar sum given by Mr. Mor- 

 rill made possible the second annual Mor- 

 rill Geological Expedition which visited 

 and collected in. the Rhinoceros beds of 

 Kansas, the Hat Creek Bad Lands and the 

 fossil Corkscrew beds in the Loup Fork 

 Tertiary of Sioux county. The party con- 

 sisted of T. H. Marsland, H. H. Everett, 

 with Erwin H. Barbour in charge. Later 

 the director of the expedition extended the 

 work of collecting to the Middle and New 

 England States. 



The third annual Morrill Geological Ex- 

 pedition, 1894, consisting of U. G. Cornell, 

 H. H. Everett, A. C. Morrill, E. L. Mor- 

 rill, J. P. Rowe, Samuel McCormick, guide, 

 Erwin H. Barbour, as director, drove from 

 Hot Springs to the Big Bad Lands of South 

 Dakota where some six or eight weeks were 

 spent, thence to the Black Hills and beyond 

 into "Wyoming and Montana. The result 

 of the expedition being that an unusually 

 large amount of material of great variety 

 including fossils, minerals, rocks, etc., was 

 secured. 



In 1895 the fourth annual Morrill Geo- 

 logical Expedition consisting of U. G. Cor- 

 nell, H. H. Everett, F. G. Hall, G. H. 

 Hall, E. F. King, J. P. Rowe, G. R. Wie- 

 land, T. H. Marsland, Francis Roush, 

 guide, Erwiu H. Barbour in charge, con- 



tinued work from the Dsemonelix beds and 

 the Little Bad Lands of JSTebraska to the 

 Big Bad Lands of South Dakota thence to 

 the Black Hills and beyond. This was the 

 largest and best equipped party sent out 

 as yet. 



In 1896 the fifth annual Morrill Geolog- 

 ical Expedition extended its work to east- 

 ern fields, spending some time in the Car- 

 boniferous of Nebraska, a week in the 

 Devonian of New York, and a couple of 

 weeks in the Silurian of Ohio and Indiana. 



In the summer of 1897 the sixth annual 

 Morrill Geological Expedition consisting of 

 B. G. Almy, U. G. Cornell, O. A. Reitz, 

 Francis Roush, guide, Carrie A. Barbour, E. 

 H. Barbour in charge, again visited and 

 collected in the Big Bad Lands of South 

 Dakota, the Black Hills region, the Little 

 Bad Lands, the Dsemonelix bed of Ne- 

 braska and beyond into Wyoming. 



In 1898, the seventh expedition was in- 

 fluenced by the Trans-Mississippi Exposi- 

 tion in Omaha, and the museum force and 

 assistants in the geological department be- 

 came interested in the preparation of ex- 

 hibits illustrating our natural resources. 

 The quarries of the State, more particularly 

 those of southeastern Nebraska, were visited 

 and important economic sets of building 

 stones, clays, soils, etc., were added to the 

 Morrill collections. 



The eighth expedition, 1899, was divided 

 into five distinct parties, two of which were 

 provided with teams and camp accoutre- 

 ments, the other parties going by rail from 

 place to place. A party of two followed the 

 Dakota cretaceous from Oklahoma to South 

 Dakota. Another drove through the quarry 

 regions in southeastern Nebraska. A third 

 party, a graduate student in the department 

 of geology, spent the summer collecting 

 Bryozoa in the Carboniferous. 



The writer with assistants, spent some 

 weeks collecting invertebrate fossils in the 

 carboniferous exposures, while the director,
