 to different plats : —

The different fertilizers were applied broadcast, and sub- 

 sequently slightly ploughed under in all cases on the same day 

 (April 22, 1891). All plats were planted in the same order

 in the hot-bed. The seeds used were in several cases sent 

 on for trial. The different kinds of garden crops were 

 arranged in the following order, beginning on the east side 

 of each plat : —
