Bearing The Camera Fell: Men would travel miles over back-breaking terrain come back empty handed. Two of the photographers had made a side trip to the Kanab Canyon did not g< single negative. 'The silver Bath had got out of ore and the horse bearing the Camera fell off a cliff a landed on top of the camera, which had been tied on t outside of the pack, with a result that need not described."14
The photographers were, successively, E. O. Beam: of New York City, who quit after eleven months in dispute; James Fennemore of Salt Lake City, who bi came ill; and John K. Hillers, the party's oarsman, wh had been trained in the field by both professionals.Compass bearings must be corrected before they can be plotted. The first correction is for deviation. This is deviation for the heading of the Boat at the time of observation, NOT for the value of the bearing—a common misapprehension! (That is, if your Boat is on a heading of 120° and the object's bearing is 0°, you must correct for your compass's deviation at 120°—not 0°. Deviation for a hand bearing compass will not be the same as for the steering compass. The former must be determined for each location from which the instrument will be used. After correction, you will have a magnetic bearing that can be plotted as such, or more often, one that is further corrected for variation and plotted as a true bearing. You should be consistent as to which procedure you use. Whichever bearing is plotted, either magnetic or true, it should be labeled immediately as described above.
A bearing is the direction of an object from the observer. A bearing may be True or Magnetic depending upon which "north" is used (uncorrected or corrected for variation). A compass bearing is one taken from the north direction indicated by the compass. A relative bearing is one referenced to the boat's heading, measured clockwise from 000° dead ahead. |
