The form of which we have just spoken is also more useful than the simple rod, because one must sometimes dig and search in the clefts of the rocks where mines are, upon the edge of steep places where boundaries may be found, and in other places where space is so limited that the smallness of the place would impede the free movement of the rod, and one would not be able to find the thing sought for, were it not indicated by the end of the forked stick, which being only one foot longer or less can easily be carried everywhere. There is still a reason which inclines us to say that this stick ought to be, it is that if in a same space, or in a small distance, there are many things of different natures hidden. As the stick would give equal move- ment for all, one would never be able to distinguish of the kinds, as we will presently shew, if the smallness of the stick does not leave us a space to pass from the place of the one to that of the other in order to observe the different causes of its movement.
