THE Marine REVIEW A 5° 37' 30" course and a %4-point course? How many of each kind of courses are there in points; in degrees? Why is NE called a 4-point course--why is it called a 45° course--why is it called a quadrantal point--why an inter-cardinal point? Why is S by W % W called a 1%4-point course? many 1!4-point courses are there? Name them. Express SSW so that it will mean the same thing in two other ways. What is the difference between SE % and S-4%- points-E? What is the difference between W 34 N and N-714-points-W? What is the difference between N-3%4-points-E and NE 3% NP If you were told to head your vessel N-5-points-W, how would your compass read? Supposing that you were told to head your vessel S 56° E, and your compass had no degree marks on it, as in the majority of cases, what course, or point, would you put her on? How What is the difference. between SSW % W and SW by S 3% S? Which is correct? What is the difference between ENE 3% E and E by N YN, and which'is correct? How"many degrees is it from S by W to ESE. What is 'the included angle between ESE and E in points and in degrees? Between SW and W by S?_ Be- tween S 34 W and SSE. The student should be as familiar with the number of points and degrees in each course as he is with its name. He should also be able to answer instantly any of the foregoing questions. No one can claim familiarity with the compass who cannot do this. Have the compass card pictured in your mind, and so thoroughly imprinted, that the moment a question is asked concerning it, either by yourself, or someone else, you can at once see the relationship existing between .the points and degrees and vice versa. | Compare correct way of boxing the compass with the "lake" method.
