properties along the Mexican National R.R. from Irapuato to Man- 
zanillo. He received every courtesy from the ranch and mine superin- 
tendents and botanized wherever possible without delaying the party 
too much. By train, stage-coach, and burros he went from Mexico City 
to Colima, past its active volcano and even to some mines in the jungle. 
He collected 782 numbers on that trip, including 40 or 50 new species. 
In 1893 he explored Nevada again, owning and operating a mine 
until the disastrous drop in silver that year. In 1894 he was appointed 
field agent of the U. S. Goy’t to explore the Grand Canyon of the Colo- 
rado. He spent the following winter in Washington, D. C. labelling 
and identifying the 4400 plants collected. As usual, he did not charge 
enough for his services. The salary he received did not cover half of his 
expenses. The report of this work is in his Cont. No. 
For the next few years all his time was spent on his monograph As- 
tragalus except for mining and business trips necessary to earn a living. 
One trip was made to San Francisco, followed by much botanizing up 
and down eastern California and up into Oregon. In 1897 he also went 
to Philadelphia to photograph the types of Nuttall’s Astragalus and on 
to Harvard and Columbia for more photographs. 
An appointment as geologist for the Pacific and Idaho Northern R. 
R. in 1899 enabled him to explore that part of the country, and later in 
the year he was made Special Statistical Agent of the Dept. of the In- 
terior to publish a book on Utah. For many years he was State Geologist 
of Utah, keeping an accurate record of the water level of Great Salt Lake, 
as well as many charts of the water-level of various irrigation districts. 
When the first case of smelter smoke damage, the Evans case, was 
tried in Utah, Prof. Jones was put in charge of the expert work. The 
smelters had so much power that no local decision was rendered, but the 
the mining interests for several years. But he never consulted his own 
interests when it was a matter of right or duty. 
Before long the Mormon farmers, realizing that he was fearless and 
incorruptible, beseiged him to fight their damage cases, and he “was 
swamped with business until 1910”. He fitted up a chemical laboratory 
in the basement of his house, made a thorough study of modern chemis- 
try by himself, collected and analyzed his own specimens of injured an- 
imals and vegetation and then served for weeks at a time as expert wit- 
ness at the trials. He gloried in a battle of wits, especially when 
championing a just cause ; so he was in his element on the witness stand 
But he was nearly 60 years old, and found the nervous strain “terrific”. 
It pleased him greatly to win his cases even though the opposing expert 
for the smelters was a university professor of chemistry. The smelters
