considerably more than 943 X 10* cubic feet of water, the guaranteed minimum,. 

 is supplied, but the size of the plantation is limited to the area whith can be irri- 

 gated during April, May and June. Consequently to increase the size of the 

 plantation it is necessary to give less than 2'5 teet so that a larger area than 

 8.6S7 acres may be watered. Under the present system of irrigating large 

 blocks it is not possible to give* much less then 2*5 feet at the first watering. In 

 May 1916 the plantation was watered using the water economically, and it was 

 found that the 3,300 acres irrigated during the month had received a depth of 

 2,375 feet. If this figure is taken as the minimum depth of water required and 

 assuming that in a dry year 946 X 10 8 cubic feet of water will be supplied 

 during April June, it will be enough to irrigate 9-.14-1 acres. The area within 

 compartment boundaries now stands at 9,191 acres so that no increase should be 

 made unless it is found that economies can be effected by a change in the 

 method of irrigation. 



The only change in method of irrigation which need be considered is one 

 which has already been urged by Canal Officers and is mentioned by ' 

 Mr. D' Arcy in para. 31 of his working plan, namely, " to sub -divide the com- 

 partments and to water each sub-division as quickly as possible." Arrange- 

 ments have been made to try this method of irrigating and if by it water can 

 be economised the Maujoki Jand Extension, should be sown up and added to the 

 irrigated area. Since 2 acres watered once a year will give a bigger yield than 

 1 acre watered twice as much or twice as often, every endeavour should be 

 made to make the water go as far as possible. It must, however, be remember- 

 ed that if the amount of water given is cut down below a certain point, in a 

 dry year a second watering would be necessary to keep the trees alive, and it is 

 quite possible that if less than 2 - 37 feet of water is given to the plantation one 1 

 irrigation in a. dry year will be insufficient. If this proves to be the case it is 

 obvious the area of *the plantation cannot be extended without more water 

 however economically it may be used.
