Indian corn is often planted with coffee or shortly before the seedlings are trans- 

 planted. Its rapid growth enables it to furnish shade even before the newly set 

 banana plants can put forth leaves. The bananas are also planted between the rows 

 of corn, which they replace when the latter is harvested. If, as generally believed, 

 the corn does not compete to the disadvantage of the coffee, this suggestion may be 

 of value in some localities where transplanting is not done in a rainy season of suffi- 

 ciently constant humidity to make temporary protection unnecessary. 



In Natal corn has proved to be a very satisfactory catch crop when "planted 

 thinly in rows, three rows, 18 inches apart, between the rows of coffee, and two 

 plants in the coffee rows between each pair of coffee plants." The cultivation nec- 

 essary for the corn is beneficial to the young coffee, which reduces but little the size 

 of the corn crop. The fertility taken from the soil by the corn should, however, be 

 returned in the form of manure.
