9135 HYDROGRAPHIC MANUAL PaGE 820 



Continuing south from the area shown on Chart 245, there is a section of coast 

 shown on Chart 1208, which is on no chart of larger scale. This section extends to the 

 eastern entrance of Cape Cod Canal, which is shown on Chart 251 (scale 1:20,000). 

 Between Chart 251 and the Barnstable Harbor chart there is another section of coast 

 shown on no chart of large r scale than Chart 1208. 



The entire section of coast from the Plymouth Harbor chart to the Barnstable 

 Harbor chart is described under the next center head, "Coast, Plymouth to Barn- 

 stable (1208)." All names to be indexed under this section are shown in bold-faced 

 type. Those which are also on Chart 251 are shown in ordinary type since they will be 

 indexed under that chart. 



No description is given here of Cape Cod Canal, for it is described in full in a 

 separate chapter. Even the controlling depth is omitted in this section, because its 

 inclusion would mean an additional correction in the Supplement every time the 

 controlling depth in the canal changed. For the same reason no mention is made of 

 the depth through the canal in describing routes out of Boston. However, to preserve 

 continuity in the text, the page where the canal is described in full is given wherever 

 the canal is referred to. 



Barnstable, Wellfleet, and Provincetown Harbors are shown on three different 

 large-scale charts which join each other and there is no difficulty in following the 

 adopted plan, in describing these places. Wliere the charts overlap and features are 

 shown on both, it is not necessary to mention that fact. If the scales of the charts 

 are the same, make the division at the most natural place. 



The final section in this chapter, ''Approaching Cape Cod (1208)," gives certain 

 information of value to the navigator in approaching Cape Cod Bay. This section is 

 center-headed and the chart number is shown as in the preceding cases. Such infor- 

 mation can be combined with that given at the beginning of the chapter and placed 

 either at the beginning or at the end.
