 this may be done properly, the director and another 

 person must station themselves on the outside of 

 the pit, transverse to each other, and so that the 

 line of sight from the point where each stands may 

 be equally at right angles to the line of the ma-

 mitted to overshoot the mark. The wheels are then 

 blocked to prevent their further advancement, and 

 the roots and branches are untied. Two ropes are 

 meantime fixed in the top transversely to each other 

 to steady the tree when set up, and the roots of the 

 under side are pulled toward the rear to prevent 

 their being broken by the great weight of the de-
