Abstract

I READ with interest the note. by Mr. H. S. Williams about the Direction Method, which appeared in the January 1961 issue of this Review (Vol. xvi, 119, pp. 18–27).The subject is an important one, and I am venturing to make some comments on Mr. Williams' note. At the outset I would say that I prefer the name “graphical” method, which Dr. van der Sterr used in his article, to which Mr. Williams refers. This is the name by which this method is more, commonly known in South Africa. I think “graphical” is possibly a more descriptive name, as the graph is such an essential part of the method, and shall use this hereafter in my comments. My comments will have particular reference to the use of the graphical method as a “break down” method in minor triangulation.
