FIRST STEPS TOWARDS AFFORESTATION 19 



A cart-road 12 feet wide should run horizontally through 

 the centre of the square, and each half of the nursery 

 be divided into 6 equal beds 21 yards wide by paths 4 

 feet wide, leaving a path 6 feet wide at either side. Paths 

 4 feet wide at the top and bottom should also be made. 

 A space for a cart to turn should be left in the centre and 

 at the end of the road farthest from the gate. 



The beds may be subdivided by paths running hori- 

 zontally if necessary, but it is a mistake to take up too 

 much space with paths. 



Soil Preparation : Draining. 



If the soil contains any excess of water, the nursery 

 must be drained. A main drain should be cut along the 

 bottom side of the nursery, and made to discharge either 

 into any existing main drain or watercourse or into a well, 

 so that the water may be utilized lor watering in the 

 nursery. An overflow pipe to carry the surplus water 

 to the nearest outlet should be laid a few inches lower 

 than the inlet pipe. The feeders or small drains should 

 run straight up the slope, with a slight bend at the 

 mouths in the direction of the flow of water in the main 

 drain. 



The distance apart and depth to cut the side drains can 

 be seen from the following table : 



Friable clay . . 2 feet 6 inches deep . . 18 feet apart 

 Medium loams . . 2 9 . . 21 

 Sandy loams .. 3 . . 30 



The main drain should be 3 inches deeper in each case, 

 and the side drains mouthed or jointed into the top of
