A Device for Determining Small 

 Elevations 



THE accompanying drawing illustrates a 

 rather simple device by means of which one 

 may make a fairly good contour map of a .hillside. 

 With it one man can determine, to a fair degree 

 of accuracy, the height of an ordinary hill or 

 the difference in elevation between two rather 

 close points, in terracing or laying out a hillside 

 garden. 



The device consists of an upright strip about 

 three inches wide, one inch thick and possibly 

 nine feet high. This is graduated to feet. Ar- 

 ranged at right angles to this and fastened in such 

 a manner that it may easily slide up and down the 

 upright, is another rod, also graduated to feet, 

 and of from five to six feet long. This had best 

 be two inches wide and of equal thickness with the 

 upright so that when fastened into position it 

 cannot be otherwise than at right angles to the 

 upright. 



To find the difference in elevation between two 

 points of the side of a hill, allow the foot of the 

 upright to rest on the lower point and slide the 

 horizontal rod so that its further end will touch 

 the hill. Then the reading on the upright will 

 give the elevation between the point, or the station, 

 where the foot of the upright rests and the point, 

 or station, where the horizontal rod touches the 

 hillside; and the distance between the two points 

 on the contour map you draw will be, in feet, equal 

 to the length of the horizontal rod. The width 

 of the upright does not here enter into our cal- 

 culation as only the side nearest the hill will touch 

 the point or station. 



The horizontal rod can be brought to a perfect 

 level by means of an ordinary spirit level and if, 

 then, this rod be so arranged that it cannot be 

 otherwise than at right angles to the upright, the 

 upright must naturally be perpendicular when 

 the horizontal is true to the level. This is really 



using the same 



method that an 



engineer employs 



with his much 



more elaborate 



equipment only that 



with this device we are 



limited to points very 



near each other. 



Plotting contour lines 

 of five or ten feet is, of 

 course, rather an inaccurate 

 and tedious piece of work, 

 though this device will be 

 found most practical to deter- 

 mine difference in elevation be- 

 tween stations running in a 

 straight line up a hill. The sta- 

 tions, however, will not be equi- 

 distant, but will be self deter- 

 mined to a great measure; for 

 the horizontal rod, when the 

 vertical is at the second station, 

 may or may not touch the hill- 

 side again with the same reading on the vertical 

 rod as it did with the vertical rod on the station 

 just below. Thus the stations could not be lo- 

 cated beforehand, but each succeeding station 

 will have to be found as one goes up the hill. One 

 could not very well say that one station is to be a 

 definite number of feet above the other, for the
