here to go into statistics and show the rela- 
tive number of chemists employed in the 
industries as compared with members of 
other scientific professions. We will admit 
without such an array of figures that there 
is no other scientific profession, with the 
possible exception of physics, which begins 
to be so numerously represented in the 
great industries as the science of chemistry, 
and even in the case of physics, aside from 
the electrical industries and those of a 
purely engineering character, the physicists 
engaged in the active industries are not 
numerous. 
When it comes to mining engineering, 
we find that the engineer himself must be 
a chemist in order to be fully able to dis- 
charge the duties of his profession. In so 
far as statistics are concerned, I will con- 
tent myself with a few citations showing 
the preponderance of chemical employees 
in the great scientific agricultural indus- 
tries of our country. 
In a study of the impress which chemical 
research has made upon agriculture, there 
has been no factor during the past twenty 
years which can compare with the work of 
the agricultural experiment stations of the 
United States. Richly endowed as they 
are by the General Government, they have 
had every opportunity to secure the best 
results for practical agriculture. 
In this work chemical science has played 
a very important part in the furthering of 
agricultural prosperity. Of the forty-nine 
directors of the stations at the present time 
twenty were professional chemists at the 
time of their appointment. The selection 
of so many professional chemists was no 
mere chance, but evidently had some rela- 
tion to the dominant position which the 
science of chemistry holds to the promotion 
of agricultural chemical research. The 
list of directors of the agricultural experi- 
ment stations of Germany shows the same 
condition of affairs. 
SCIENCE. 
(N.S. Vou. XIII. No. 332. 
The great influence of chemistry on the 
agricultural experiment stations of this 
country is not measured alone by the num- 
ber of professional chemists which is found 
in the directorates, but also by a comparison 
of this number with that of other scientific 
men holding similar positions. Very few 
of the other sciences are represented among 
the directors of stations, and no one of them 
can compare in its number of representa- 
tives to the science of chemistry. Among the 
working forces of the stations chemists also 
predominate. There are twice as many 
chemists employed in the stations as there 
are men engaged in any other professional 
scientific work. Statistics show that the 
number of chemists employed in the agri- 
cultural experiment stations of the United 
States is one hundred and fifty-seven, while 
the number of botanists is fifty and the 
number of entomologists forty-two. The 
number of employees belonging to other 
branches of science is very much less than 
that of the botanists and entomologists, 
and the total number of scientific men em- 
ployed in all other branches of scientific 
work in the station does not greatly exceed, 
even if it be equal to, the number of those 
employed in chemical research alone. 
While dwelling upon the predominance 
of professional chemists in the directorates 
and upon the staffs of the experiment sta- 
tions, it seems eminently proper to mention 
here in a special manner some of the earlier 
eminent chemists who have contributed so 
much to the value of chemical research in 
our agricultural colleges and experiment 
stations. Among these must be mentioned 
Professor F, H. Storer, of the Bussey Insti- 
tute (Massachusetts), who first began the 
regular publication of a bulletin recording 
the work of the school and station, which 
has ‘ set the step to which the bulletins from 
many other stations are still marching.’
