234 EXPERIMENTS ON WHEAT,1 jPart II. 



being exadtly fix inches each, 96 clufters were fowed in each row, 

 which made 1 6 clufters over and above. By this means, feveral of 

 them were nearer than fix inches to one another. 



♦' Two hundred and eighty-eight clufters were fown, all of which 

 produced plants, except 25 which did not fprout, or of which the 

 plants perilhed. This deficiency is not very confiderable : but we 

 muft obferve, i . That almoft all the places where this happened 

 had been fown with only one or two grains of wheat : 2. That it 

 was in the middle row that the greatefl number of plants was 

 wanting: 3. That the fouth row, in which the fmalleft quantity 

 fown for any one tuft was three grains, furnifhed and retained its 

 full number of plants : and laftly, that almoft all thofe which were 

 next to the vacant fpaces, were ftronger than the reft, and thereby 

 made amends for the lofs of the others. 



*' Secondly, The whole number of the ftalks amounted to 5189, 

 which is after the rate of 43 ftalks and a quarter to a foot : but it 

 is much more confiderable in the fouth row, which having pro- 

 duced in all 2225 ftalks, the proportion is 55 and a half to a foot. 

 The caufe of this difi^erence is eafily feen. The expofition of that 

 row, to the fouth, being more favourable than that of the others, 

 may have contributed thereto; but it is very plain that it was chiefly 

 owing to none of the clufters in that row being fown with fo few 

 as one or two grains. 



" Thirdly, We fee that the increafe of the ftalks was, in general, 

 in proportion to that of the feed; only the clufters that were fown 

 with three grains in the fouth row, produced 46 ftalks more than 

 thofe which were fown with 4 grains; but ftill the general refult of 

 the three rows remains exadlly in the fame progreflion, as appears 

 by the following recapitulation.
