feet by two feet, three feet by three feet, and three feet by two 

 feet respectively. Another set of holes were dug two feet by eighteen 

 mches wide and eighteen inches square but only eight inches deep at a 

 distance of four feet by three feet and three feet by three feet apart ; 

 trash and manure were applied to one-half of these holes as is usually 

 done, whereas no trash or manure was put in the others which were 

 simply refilled with loose earth from around and the soil drawn up in a 

 hill over the holes. 



The results obtained are given below ; —

Although the soil at St. Augustine is a faily loose sandy loam it was 

 found last yea-r moi-o profitable to have deep holes i.e. eighteen inches 

 than shallow holes i.e. eight inches deep, notwithstanding the higher 

 cost of preparing the deep holes. The experiment was repeated this 

 year and similar results were obtained as can be seen by comparing the 

 results of plots 1 and 2 with those of plot 8, and plots 3 and 4 with plot 6. 

 Deep holes four feet by three feet and three feet by three feet gave a 

 net profit of $421-55 and $7-26-23 per acre against $389-31 and 1472-29 

 respectively from the shallow holes. It will also be seen that it is more 

 profitable to fill the holes with trash and manure, as not only has a 

 larger yield b2en obtained but the value of the increased crop is more 

 than sufficient to pay for extra cost of procuring and filling the holes- 

 with trash and manure, vide plots 1 a id 2, 3 and 4.
