The next objective will be Lake Rocagua, in which region they expect 

 to spend a month or more exploring and collecting. Other important 

 collections will be made in the Valleys of the Rio Beni and the Mamore. 

 The Mamore River will be visited with the special object of exploring 

 the region which yields Brazilian Ipecac. Temporary headquarters will 

 next be established at Villa Bella, the western terminus of the Madeira- 

 Mamore Railroad. The party will so arrange their work and time their 

 journey as to reach Manaos about November of this year.. Here they 

 will receive large shipments of supplies for the second half of the jour- 

 ney and send home the collections already made. 



According to present plans the party will then start out from Manaos 

 early in 1922, ascending the Rio Negro and Rio Uaupes, for the purpose 

 of exploring and collecting among the upper waters of the latter river 

 and in some of the valleys and ravines along the eastern side of the 

 Andes south of Bogota, Colombia. After crossing the mountains to 

 Bogota, they will finally emerge at the coast at Barranquilla for their 

 return journey. 



Perhaps no other expedition that has gone into South America has 

 ever entered the tropics so well protected medically against possibilities 

 of fevers, skin diseases and the numerous tropical affections. These in- 

 clude great quantities of Antidysenteric Serum, for the prompt treat- 

 ment of cases of dysentery, should any of the members of the party 

 contract that disease, a rather unlikely event, if all the members make 

 the proper use of the means provided for the sterilization of the drink- 

 ing water. Antipneumococcic Serum and Antitetanus Serum are also 

 included among the supplies. Most important, however, is a quantity 

 of Anti-snake-venom, which the Mtilford Company took special pains 

 to prep-are for Dr. Rusby's party, and which they are supplying to them 

 in small, sterile, hypodermic syringes, ready for instant use when occa- 

 sion requires. 



Members of the party have further protected themselves against dis- 

 ease by taking certain preventive measures. These include the well- 

 known measures of vaccination against smallpox and the prophylactic 

 inoculations against Typhoid Fever, the effectiveness of which no long- 

 er remains a matter of doubt. In view of the prevalence and dangers 

 of pneumonia to which they are exposed, especially in the highlands of 

 Bolivia, the members of the party have been provided, with an Anti- 

 pneumonia Vaccine, which should give them considerable protection, for 

 some time at least. If it gives them a moderate protection against pneu- 

 monia for even six or eight weeks, this will carry them over the most 

 dangerous period, i. e., until they have crqssed the Andes and have 

 descended from the highlands of Bolivia to the great plains. They are 

 also supplied with various insecticides and repellents, which they will 

 use to obtain relief from the annoyance of incessant attacks of hordes 

 of insects.
