The recorder enters on each tag the information called for, 
using a soft lead pencil except in the case of haul numbers, 
which being in sequence irrespective of the nature of the haul, 
are written in India ink previous to sailing. However, to provide 
against loss of tags, a few tag-books are carried in duplicate in 
which the haul number is not designated. When a tag is prop- 
erly filled out it is placed inside the jar containing the haul, and 
formaline (about 10 per cent) is added, or when practicable the 
hauls are carried to the laboratory without killing. In addition 
to the tags a log-book is kept in which is also entered the same 
data for each haul and water sample, together with the details of 
operating the apparatus, accidents, weather conditions, and in 
fact anything that might have the remotest bearing on the 
results. Upon completion of the day’s work the recorder checks 
the entries in his book against those the captain has kept. As 
soon as possible after the material has reached the laboratory the 
data for each haul and water sample are typewritten in triph- 
cate upon accession sheets. Each accession sheet for hauls is 
17 by 14 inches in size and ruled into columns having the follow- 
ing headings: haul number, character of haul, apparatus used, 
date, time of day, station, position, depth of haul, nature of 
bottom, water-sample number, temperature (during haul, at 
surface, in air), remarks. The accession sheet for water-samples 
is of the same size and bears the following headings: water 
sample number, date, time of day, haul number, position, depth, 
temperature, and many other headings for entries of density, 
chlorine content, salinity, ete. 
Experience has taught that the recorder should not attempt 
anything else than his particular task when thus engaged. Hauls
