 184. "A Method how to find the distance to 

 44 which roots extended horizontally. A piece, or 

 "plot dug and made fine, in whole hard ground ^ 

 "as in. Plate II. Fig. 1. 



" The end A. 2 feet, the end B. 12 feet, the 

 ** length of the piece 20 yards ; the figures in 

 44 the middle of it are 20 Turnips, sown early 

 " and well hoed. The manner of this hoeing 

 " must he, at first, near the plants, with a spade, 

 44 and each time afterwards, a foot distance, till 

 44 the earth be once well dug; and, if weeds 

 44 appear where it has been so dug, hoe them out 

 44 shallow with the hand-hoe. But, dig all the 

 44 piece next the out-lines deep every time, that it 

 44 may be the finer for the roots to enter, \vhe% 

 44 they are permitted to come thither. If the 

 44 Turnips be all bigger, as they stared nearer to 

 the end B, it is a proof they all extend to the 

 outside of the piece, and the Turniji 20, will 

 appear to draw nourishment from six foot dis- 

 tance from its centre. But if the Turni/is 16, 

 17, 18, 19, 20, acquire no greater bulk than the 

 Turniji 15, it will be clear, that their roots 

 extend no farther than those of the Turniji 15 

 does ; which is but about 4 foot. By this method 

 4 the distance of the extent of roots of any plant, 

 4 may be discovered. There is also another way 

 to find the length of roots, by making a long 

 narrow trench, at the distance you expect they 

 will extend to, and fill it with salt ; if the plant 

 4 be killed by the salt, it is certain that some of 

 >4 the roots enter it.
