October. On the 14th October the (d) plots were thinned, 

 and on the 17th both (c) and (d) were earthed-up. The winter 

 was severe and only about forty per cent, of the transplanted 

 seed (b) survived, whereas (c) and (d) suffered but little. The 

 development of the roots and shoots on (b) was, however, 

 much better than on any of the other plots, and when the crop 

 was reaped the number of stalks per plant on (b) averaged 

 10, as against 4 on (a), 7 on (c), and 8 on (d). The number 

 of full ears per plant and the number of grains in the ear 

 were also greater than on the other plots. The average 

 results are given in the following table : —

It will be seen that the transplanted rye gave the smallest 

 yield, which was attributable to the wide planting in the 

 first instance, and was further reduced by the thinning- 

 out caused by the unfavourable winter. The same reason 

 accounts for the poor yield on (d). The yield, however, of 

 the earthed-up plants on plot (c) differs very little from plot 

 (a) and could not be regarded as remunerative. 



In the case of barley, the arrangement of the plots was the 

 same, but the distance between the plants and rows was some- 

 what different. In plot (a) the rows were 12*5 cm. (nearly 5 

 inches) apart ; in plot (b) the transplanting was done in four 

 rows 7 cm. (2§ inches.) apart; with an interval of 30 cm. 

 (nearly 12 inches) between each set of four rows, the plants 

 being 10 cm. (nearly 4 inches) apart; in plot (c) five rows 

 were drilled about 8 inches apart with an interval of 12 

 inches between each set of five rows ; on plot (d) the rows 

 were drilled in the same way, and the plants were thinned out 

 to 4 inches apart. 



Sowing was done on 8th April, transplanting on the 4th 

 May, thinning-out and earthing-up on the nth May. The 

 transplanted seedlings suffered very much from unusual
