feet, and each plat divided into four ecjual sections. It will 
be seen that each plat included one-twentieth of an acre, and 
each section one-eightieth of an acre in area. The plants 
were set three rows to the plate, four feet between rows and 
two feet apart in the row. There are a number of different 
methods of planting in vogue, but as the writer's idea was to 
employ the one most widely in use in Hawaii the above method 
of planting was decided upon. The plats were set six feet 
apart so that a space of ten feet intervened between the outer 
rows of. any two plats. This is not common practice, but was 
done so that under these conditions there was no danger of 
the pineapple roots from one plat penetrating to another and 
obtaining nourishment not intended for them. Plats 1, 5 and 
9 w^ere check plats. N^umbers 2, 3 and 4 were treated with 
superphosphate, steamed bonemeal and reverted superphos- 
phate, respectively. Plats 6, 7 and 8 had applications of ni- 
trate of soda, sulphate of ammonia and steamed hoofmeal, re- 
spectively. The potash plats, 10, 11 and 12, were treated with 
muriate of potash, sulphate of potash and sulphates of potash 
magnesia, respectively. These ingredients were applied singly
