The early trimmed plants gave con.siderably less yield than the 

 late trimming or the cheek. There was no constant difference in 

 earliness. The figures, as they stand, seem to teach that the 

 plants had better not have been trimmed, for although there is a 

 trifle gain in the late-trimmed lot (No. 3), the increase is not 

 enough to make one feel sure that it is due to the treatment. In 

 1890, however, trimming on July twenty-eighth and August 

 twenty-fifth gave considerably increased productiveness and earli- 

 ness. In 1891, the trimmings were made AugiLst third, August 

 twenty-fourth and Septembei' eighteenth, and the results were 

 indiff'erent; it was then thought that the unsatisfactory yields 

 were due to the lateness of the trimming, but the first trimming 

 this year was made on the same date as in 1890, but with opix)- 

 site results. So we aire still in doubt as to whether tiimming 

 promises any benefit; but it is evident that it does not yield 

 decided results. 



15. Single-stem training. — A good number of Ignotum plants 

 were set a foot apart, in rows, and each plant was tied up to a 

 perpendicidar cord, but one stem or stalk being allowed to gi\)w 

 in each case. The first tying of the stem to the wire was made 

 July twentieth, the plants having been set June fir.st. I'l-obably 

 earlier attention should have been given to this. Thereafter the 

 plants were tied every week or two, as occasion required, but this 

 attention was not arduous. Other plants of same age and variety 

 were set alongside, four by four feet apart, for comparison.
