A SKETCH OF HtS LIFE

the large number of papers which they published. Doctor Brooks 
expected all of his graduate students to spend a season or more 
at this laboratory. He rightly estimated such work as the most 
valuable experience a beginner could have, for in this way the 
student became acquainted with animals under natural condi- 
tions; he had the opportunity of laying a broad foundation for 
his future work as a naturalist, of finding for himself some matters 
to investigate, and thus early to acquire the mental habit of the 
independent investigator. 
The Chesapeake Laboratory, as said, was not limited to one 
place. For the first few years of its existence it was located at 
several different points on Chesapeake Bay; afterwards it was 
located at Beaufort, North Carolina; then at different places in 
the Bahama Islands, and finally in Jamaica. In the various 
expeditions of Brooks and his students to these different places 
they made not only a biological survey of each region, but they 
did work of most fundamental and far-reaching importance 
on the various groups of animals found. Out of these expeditions 
has grown the beautiful and permanent station of the U. S. 
Fisheries Bureau at Beaufort, North Carohna, in which Brooks 
took great interest and pride. It was on these expeditions that 
his students came to know him most intimately and affectionately. 
In the memory of each of them is fixed some scene of his enthu- 
siasm over the discovery of a rare form or of an unknown stage in 
some life history; his long vigils full of exciting discoveries; his 
quiet talks on nature and philosophy. 
The Chesapeake Zoological Laboratory occupied so large a 
place in the life and work of Professor Brooks that it seems desir- 
able to reproduce here, in his own words, a more detailed account 
of the aims and history of that laboratory during its first nine 
years. The following is taken from a report by Professor Brooks 
on ''The Zoological Work of the Johns Hopkins University, 1878- 
86," published in the Johns Hopkins University Circulars, vol. 
6, No. 54: 
In natural science the policy of the University is to promote the study 
of life, rather than to accumulate specimens: and since natural laws are 
best studied in their simplest manifestations, much attention has been
