or pipes should still be in good repair, and if the site 

 of the plantation has been well chosen, as regards 

 soil and position, seepage troubles should not have 

 made an appearance in so short a time. 



I have estimated the total life of the trees at 

 30 years. The first six years as a period of infancy, I 

 the time from the seventh to tenth years as the age 

 of coming into bearing and paying working expenses 

 and somewhat over, and the period from the tenth 

 to thirtieth years as the age when in full bearing. 

 During these last 20 years an annual allowance of 

 2 per acre has been debited for depreciation on 

 harvesting plant, channels, and for provision for 

 drainage, as well as an additional depreciation of 

 5 per cent, per annum on the capital outlay of 85. 



In the estimate I have calculated the average 

 crop at 200 cases per acre, commencing in the tenth 

 year of the orchard's existence, and continuing at 

 that rate for the following 20 years :
