ordinary interest and value. Through the kindness of Mr. I. H. 

 Burkhill, Reporter on Economic Products, and Mr. Hooper, the Curator, 

 as well as that of Captain Gage, Superintendant of the Botanical 

 Garden at Sibpur and Mr. Ralph H. Pearson, Forest Economist at 

 Dehra Dun, relations were established that will prove of great value 

 in the future acquirement of exhibition material. In India con- 

 siderable additional material was secured at Benares, Delhi, Agra, 

 Jeypur, Bombay, Madras and Madura. At Kandy, Ceylon, co-op- 

 erative relations were established with the Botanic Garden at Peridynia 

 through the kindness of the Acting Director, Mr. R. H. Locke who has 

 since sent in some very important and interesting specimens for instal- 

 lation. Returning via Europe a few days were spent in Munich in 

 drawing out some one thousand herbarium specimens from the collec- 

 tion of duplicates of the older Bavarian collectors. 0. E. Lansing, 

 Jr., of the Department has continued, at odd intervals, to collect plants 

 of the Lake Chicago Basin in Illinois and Indiana. He has also made 

 several trips afield to secure living material for the use of the Section 

 of Modeling; and has made a trip to Vermilion County, Illinois, and to 

 Richland County, Wisconsin, principally to secure herbarium material 

 for exchanges. The dendrologist, Assistant Curator Huron H. Smith, 

 has continued, his work of securing specimens of Pacific Coast trees 

 during the past year ; he has sent in a number of shipments of material ; 

 and has continued to collect herbarium specimens at each of his stations. 

 The material is not yet organized and therefore does not appear 

 in detail in this report. The Assistant Curator of Invertebrate 

 Paleontology examined a number of exposures of beds of Maquoketa 

 age in Fayette County, Iowa, and procured about one thousand 

 specimens there. Of these specimens about 550 were brachiopods, 

 200 trilobites, 100 crinoids and cystids, and the balance corals, 

 sponges, pelecypods, gastropods and cephalopods. Special attention 

 was paid to the collecting of trilobites in the region with the result 

 that two new species were obtained and much additional material 

 secured which will throw light on the structure of previously known 

 species. Two new species of crinoids were also secured. This 

 material, taken in connection with that obtained by the trip to the 

 same locality in 1910, affords specimens upon which the description 

 of one new genus and eleven new species of trilobites and one 

 new genus and four new species of crinoids and cystids will be 

 based. Of twelve of these the Museum will possess the types. 

 Material for re-description of six previously known species of trilobites 

 was also obtained. Besides material of descriptive value, some good
