Reports of Scientists From Five
 Trips Are Turned in

Chicago Aug. I (By the Associated Press Reports of interesting scient- fic discoveries are beginning to come In from five expeditions which have been sent out this year by the Field Museum of Natural History. to fer ret out secrets of tho worlds past that are buried Tn rocks or hidden away in spots that are almost inacces- sibe, A sixth expedition will soon start Most Of this work Is to be done in portions of South America where there has been but little scienti- fic exploration,
 A geological expedition under the direction of l, Oliver c. Harrington is now proceeding into the interior of Brazil toward the upper reaches Of the Amazon to obtain a series of minerals relating to the diamond in an endeav- or to trace, if possible, the primary rocks which are the source of the diamonds. The diamonds of Brazil differ in their occurrence from those in other parts of the world in being found in highly quartzose or granite rocks. In all other important dia- mond bearing rock localities the prim- are source Of the diamond is rock composed magnetism silicates and containing no free quarts It is also hoped to procure full series of the rare Brazilian diamond accompanying materials which are not found else where.
 Out Collecting.
 Two botanical expeditions and one geological expeditions have been in the field for "a number of months. One of the botanical expeditions left the United States early in March. under the guidance of Dr. B. E. Dahlgren, for British Guiana to collect speci- mems for plant reproduction and econ- omic botany.
 A botanical and geological expedi- tion landed at Callao, Peru. the latter part of April and after a short stay in the coastal regions crossed the Andes to work on the eastern slopes until early fall, when they will start down the tributaries of the Amazon and thence down the Amazon to the ,, Atlantic.
 This combined expedition VII, eh- counter many varied geographic and climatic conditions. At times they will be in lands where both plant and animal life is exceedingly sparse and at other times they will be in the dense jungles of the upper Amazon.
 To Work Mountains.
 Again they will work in regions near the tops of the mountains where climatic conditions will be those of the extreme southern end of the contin- ent, and later they will encounter the torrid climate of the equatorial re- gions whn they reach the iungles. Some of the country they will ex- plore contains what are virtually Hand islands" for they are completely sur rounded by high mountains, and con- tain animal plant life little known to the outer world.
 Many rare and interesting speci- mems are being gathered by these expeditions. which are under the lead rship of Edmund Heller, noted South American and African explorer who was with Theodore Roosevelt on >hls expedition into Africa accompanying MT. Heller are John T. Trimmer, J Francis MacBride and William Feath- erstone. all of the Field Museum of Natural History
