Harem charts. — Graphic representation of the size and extent of the fur-seal herd 

 has usually consisted in the coloring or shading of the areas occupied and in distinguishing, 

 so far as possible, the breeding areas from the hauling grounds. For various reasons, 

 this has proved unsatisfactory as an accurate measure of the herd, although for general 

 comparisons it has been valuable. All such devices, to be of permanent value, should 

 be based upon data which can be stated in exact terms and which utilizes fixed marks 

 or natural features that can be identified by future observers. 



Before the investigation of 1914 was begun it was found that unpubUshed charts 

 showing the number and approximate position of the harems on each rookery had been 

 made in 1912 and again in 1913 bySpecial Investigator G, A. Clark, These charts showed 

 the contours of the topography as surveyed by the United States Coast and Geodetic 

 Survey and also indicated the position of the rocks on which conspicuous numbers were 

 painted at the time of the survey. These charts were so obviously based upon sound 

 method and their comparative value was so evident that their use was continued in 191 4. 

 Blank copies were carried to the rookeries while the harem counts were being made and 

 the position of the harems with reference to the marked rocks was roughly indicated by 

 pencil notes. Immediately thereafter duplicate copies were made transcribing the notes 

 in uniform style for all the rookeries. The field charts thus made have been the basis 

 of the charts published with the present report. The scale is necessarily too small to 

 show the exact position of each harem, but the number and approximately the arrange- 

 ment of harems between any two numbered rocks is according to the facts.
