that you are principally interested in the construction of 

 the sheds. 



As to the cost of this shed, it would be pretty hard 

 to come at it, as we had to make it over from another 

 style. But I should say that a shed on this plan could be 

 built for f 800 per acre. 



Trees in this shed are twelve and a half feet apart 

 each way. There are 735 of them; varieties, Pineapple 

 orange, Triumph pomelo and Dancy Tangierine. 



Cost of firing is the same per acre as in the Clifford 

 shed. (Four acres |14 per night with wood, |9 with 

 coke.) 



This shed is opened and closed by two men walking 

 on top, taking hold of each end of a panel and raising 

 or lowering it as the case may be. It cannot be operated 

 quite as rapidly as the Clifford shutter-shed. It takes two 

 men half a day to go over the whole shed. But in the win-

 days. Every night in winter we have at least half of the 

 cover down, so as to be able to close the rest quickly if it 

 should be necessary. J. A. Stevens.

 SUMMER. 



"Af ter having tried several other methods of protecting

 grove. Such were the results of the first trial on three
