260 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 1 



much to the fore, but most of the records here are photographic. The 

 locations are usually associated with the shore stations, but they are not 

 referred to in this list. 



In the first long cruise, 1931-32, collecting for the Foundation was 

 rather incidental and was confined to shore and inland collecting near 

 each anchorage used. These stopping places have been numbered in order 

 and the geographic position is given for each ; however, the numbers have 

 not the same meaning as the numbers for the later stations. For that 

 reason, numbering for actual collecting stations was again started at "1" 

 on the next cruise, and these have been continued in chronological order 

 since that time. 



On the second cruise, starting in late December, 1932, shore collecting 

 was still the chief means of obtaining specimens, although diving, sein- 

 ing, setting lobster traps, and collecting coral heads brought good results. 

 Dredging by hand from a motorboat helped out materially. 



On the third cruise, December, 1933, to March, 1934, better equip- 

 ment for dredging really started a new era. One of the ship's motorboats 

 was fitted up with a power winch, shearlegs, and sorting table and was 

 provided with 250 fathoms of steel cable for dredging. This worked very 

 well and has been used, with some slight changes, ever since. 



In 1938 the Velero HI was equipped for dredging, and this equipment 

 has been used extensively for dredging in deeper water and in shallower 

 water, as well, if the bottom is not too rough. 



For shore stations and for those where the motorboat is used, readings 

 of latitude and longitude have not been taken directly, but have been 

 determined from the position of the starting point as shown on the hydro- 

 graphic charts. They are not of uniform accuracy, as the charts vary 

 much in scale. 



Since the Velero III has been in action for dredging, the exact position 

 can readily be determined, and it has been so determined at the beginning 

 and the end of the haul. The depth (fathometer reading) also is taken at 

 these times. 



When the small dredge is used, the haul is usually short, and two or 

 more are often taken in a restricted area with depth and bottom similar 

 over the area, in which case both or all of these hauls have been included 

 as a single station. When the large dredge is used from the Velero III, 

 the hauls are usually longer; however, if more than one haul is made in a 

 restricted area, with depth and bottom similar throughout, the same 

 station number is used throughout, but the hauls are distinguished by 

 letters, a, b, et cetera, following the number.
