NO. 1 GEOGRAPHICAL ACCOUNT AND STATION RECORDS 29 



The list, then, includes ( 1 ) dredging stations occupied by the Velero 

 III, (2) dredging stations occupied by the dredge boat, (3) shore collect- 

 ing stations between tide levels, (4) beach seine hauls, (5) miscellaneous 

 diving and dipping, and (6) hook-and-line fishing, and purchases from 

 natives of freshly caught fish. Much of the dipping was done at night 

 under a cargo light suspended from the gangway. 



In the case of dredging stations occupied by the Velero III the data 

 are most complete and consist of a start and a finish position, time, and 

 depth, and the general direction of the haul. Positions were obtained by 

 cross bearings when possible, or by a single bearing and fathometer read- 

 ing. The depth was obtained by fathometer. In the case of stations occu- 

 pied by the small dredge boat, which was without instruments of naviga- 

 tion other than compass and lead line, the data are less complete and less 

 accurate and consist of a starting position only. Likewise, upon the small 

 charts accompanying the station list, Velero III dredging stations are 

 indicated by arrows showing start, finish, and direction of haul, whereas 

 small dredge boat stations are indicated merely by a cross showing the 

 starting position. An exception is the chart of Caledonia Bay, which was 

 of sufficiently large scale to permit the plotting of both start and finish 

 positions of the small dredge hauls. 



Often more than one haul w^as made to a dredging station, it being the 

 custom to change numbers only with a marked change in position or char- 

 acter of the bottom. In the case of Velero III dredge hauls these are indi- 

 cated by D-1, D-2, etc. In the case of the small dredge these are not ind'i- 

 cated except again at Caledonia Bay, and there only on the chart and not 

 on the list. Specimens from the various dredges of one station were com- 

 bined, regardless of whether taken by the Velero III or small dredge boat, 

 but the full data of each haul were preserved in order that scientists 

 working over the collections from a given station might know that the 

 station represented a fair sampling of the area, rather than a single cross- 

 section. 



The designation "a," as in station A44a-39, is employed in quite 

 another sense than are D-1 and D-2, which indicate fractions of the same 

 station, specimens of which were not kept separate. It occasionally hap- 

 pened that two collectors, working independently, each assigned the next 

 consecutive station number to specimens taken at widely separated local- 

 ities. When this error was discovered, it was rectified by adding the small 

 letter "a" to one of the stations, thus requiring a minimum alteration of 

 specimen labels. It therefore is the equivalent of an independent station 

 having no relation to the station of the same number without the "a."
