92 THE AMERICAN GARDENER. [Chap 



England, from having, when in France, observed 

 the effects of inner-tillage on the vines, in the vine- 

 yards. If he had visited America instead of France, 

 he would have seen the effects of that tillage, in a 

 fitill more striking light, on plants, in your Indian 

 Corn fields; for, he would have seen these plants 

 spindling, yellow, actually perishing, to-day, for 

 want of ploughing ; and, in four days after a good, 

 deep, clean and careful ploughing, especially in hot 

 weather, he would have seen them wholly change 

 their colour, become of a bright and beautiful green, 

 bending their leaves over the intervals, and growing 

 at the rate of four inches in the twenty-four hours.

 them from TULL, and give them, with all the honour 

 belonging to them, to a Bishop.

 roots extend horizontally. A piece, or plot, dug 

 and made fine, in whole hard ground [Plate II. 

 Fig. 1.1 the end A. 2 feet, the end B. 12 feet, the 

 length of the piece 20 yards ; the figures in the mid- 

 dle of it are 20 Turnips, sown early and well hoed. 

 The manner of this hoeing must be, at first, near 

 the plants, with a spade, and each <ime afterwards, 

 u foot distance, till the earth be once well dug ; and, 

 if weeds appear where it has been so dug, hoe them 

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

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

 may be the finer for the roots to enter, when they 

 are permitted to come thither. If the Turnips be
