PATHS 67 



being of convenience in passing and when the walks are 

 crowded. The depth of the gravel is 4 inches. The 

 gravel should be of such a character that it will readily 

 bind. It should be of suitable color and its surface should 

 be continuous with that of the middle portion of the walk. 

 Crushed stone will not answer for this purpose. 



(4) Entrances. Where a park walk joins an exterior 

 walk on the center line of a street, the street center line 

 produced should coincide with a tangent to the center 

 line of the walk at the point of entrance. If so designed 

 the entrance will look correct to a person driving down the 

 street toward it and will afford equal ease of access to the 

 park in both directions. (See Fig. 23 on page 66.) 



Corner entrances should be so laid out that they may 

 be equally easy of access from both street cross-walks. 

 This is illustrated hi Figs. 24 and 25, on page 68, the first 

 showing the correct design and the second the incorrect. 



Cement Paths. Interior walks are crowned in the 

 middle. The crown is of two lands, straight and curved. 

 The first consists of two planes intersecting on the center 

 line of the path; the second of a continuous curved surface 

 with high point hi the center as before. The first method 

 is to be preferred, as there is less likelihood of puddles 

 after a shower. (See Fig. 15 on page 47.) Crowns are 

 usually made too high. A crown of J of an inch in a walk 

 8 feet wide is ample if it is actually secured. The impor- 

 tance of careful staking out cannot be over-emphasized. A 

 little extra outlay for more grade stakes will more than pay 

 for itself. It is in this connection that a criticism can be 

 made in regard to the construction of our rural highways. 

 In the effort to provide thorough drainage most extravagant 

 crowns are adopted crowns which frequently endanger 

 traffic. By the employment of a small surveying corps
