Nov. 29. Tide register corrected at noon. Sounding at noon 7 fath.,0 feet, 4 inches, register 18.2. It may be 

 remarked that soundings are subject to uncertainty in case of any drift of the ice field in which the vessel was 

 imbedded, and also in case the bottom be soft. 



Nov. 30. Sounding at noon

Some allowance must be made for stretch of the line. 



(This sounding was not used, apparently not reliable.) 



A mean correction was used for these days, as deduced 

 from enveloping curves and the soundings.
