Nelson and Goldman drove through the southern end of the San 

 Joaquin Valley to a site 8 miles west of Tejon Pass and thence to 

 the head of San Emigdio Canyon. Leaving this camping site they 

 crossed the southern end of the valley, collecting at various localities 

 on their northward trip to San Luis Obispo, Calif. From this place 

 they worked northward to San Simeon and the mountains near by, 

 and in a few days drove southward along the coast, collecting sea 

 birds particularly, to Santa Paula, where, about January 4, 1892, 

 they abandoned the buckboard and field outfit. 



Orders had been received from Dr. C. Hart Merriam, chief of the 

 Bureau of Biological Survey, for Nelson to start on what it was 

 anticipated would be a three months' trip to western Mexico. Nelson 

 and Goldman traveled by rail from Santa Paula to San Francisco 

 and sailed on the Pacific mail steamer Acapulco for Manzanillo, 

 Colima, where they landed on January 24, 1892. From the time of 

 sailing until March 1, 1892, Goldman, who had previously been a 

 personal assistant of Nelson, worked for the experience without pay, 

 and then he received his first official appointment from the Biological 

 Survey, which authorized his employment at $75 a month, out of 

 which he was to pay his board and traveling expenses. Instead of 

 lasting three months, the field trip was extended, until Goldman had 

 passed four years in Mexico, after which he received permission to visit 

 his home. 



In September, 1893, Nelson left Chihuahua City for Washington, 

 D. C, but returned to the City of Mexico in December, 1893, where 

 he was met by Goldman, and they continued the field work together. 

 Again on August 15, 1896, Nelson left Carneros, Coahuila, for Wash- 

 ington. The same year, Goldman received permission to visit his 

 home in California, and he accordingly left Santa Rosa, Guanajuato, 

 on November 18, 1896, for Alila, Calif., but resumed field work at 

 Rio Verde, San Luis Potosi, on January 7, 1897. Nelson rejoined 

 Goldman at Ameca, Jalisco, on February 6, 1897. Field work for 

 that season was completed on September 17, 1897, at Bolaiios, 

 Jalisco, where Goldman left to revisit his home in California and 

 Nelson to return to Washington. Goldman, on his return to Mexico, 

 went to the Valparaiso Mountains in Zacatecas, where he began 

 collecting on November 26, 1897. Doctor Nelson rejoined him at 

 Altamira, Tamaulipas, on April 24, 1898. 



About September 20, 1898, Nelson left Goldman at Parral in Chi- 

 huahua and returned to Washington, while the latter proceeded 

 across the Sierra Madre. Again, on June 3, 1899, Nelson met Gold- 

 man at Casas Grandes, Chihuahua, and the two continued to collect 

 until October 7, 1899, when they discontinued field work for the season 

 at Sierra en Media, Chihuahua. Goldman again left for California 

 and while there did some collecting. About December 30, 1900, he 

 arrived in Arizona and began field work near Winslow, the main
