Mr. Livingjlon's Experiments on Lucerne* 89 



Thefe two obfervations point, firft to the foil in which it 



fliould be fown; to wit, a warm dry foil in tolerable heart; and 



fecond, to the means of procuring the warmth which I fpeak 



of as neceffary to the plant ; this may be obtained in two ways : 



ill, by dung ; and, 2d, by fowing when the fun has given the 



earth an addition?.! heat. If fpring fowing is intended, I fhould 



prefer ground that had been manured and bore a potatoe crop 



the year preceding, becaufe by that means the weeds which 



the dung produces will have been deftroyed by the hoeing of 



the potatoes. Ifnofuch ground is ready, and a fpring fowing 



is intended, the dung fliould be ploughed in July or Auguft, 



and the ground harrowed fine ; this will bring the weeds 



forward, when a fecond ploughing, and the winter will deftroy 



them before they have perfected their feeds ; the lucerne may 



be fown early in May (2olb. to the acre) after the ground has 



had three or four fpring ploughings with barley, which will 



pay the expence of the manure and ploughings. 



Second mode by which the feeds will come up quicker, and 



v/ith more regularity, is to manure early in the fpring, and to 



plough and harrow the ground fine when the weeds have 



fprung and got fome head ; and when the earliell kinds begin 



to blolfom, plough again and harrow fine; repeat this four times 



by the ifl of July, when the lucerne feed fhould be fown (i61b. 



to the acre) every feed of which will then vegetate : The feed 



fliould always be fown when the ground is dry, and rolled in,
