FROST PROTECTION. 371 



We have the shed arranged now so that we can cover 

 one acre at a time, and can do it in seven or eight minutes. 

 It is the most satisfactory cover I have seen. G. W.

COVERED GROVE AT CITRA. 



The Barney shed, covering three acres, was originally 

 built on the same plan as the Clifford shed, but because of 

 the difficulties of operating that style of cover, as enumer- 

 ated in my letter describing the Clifford shed, this has 

 been made over. The framework of this shed divides the 

 area covered into squares of twelve and a half feet each, 

 and where two swinging shutters of 6x12 feet each origin- 

 ally filled the square, these two swinging shutters have 

 been made over into three panels of 4x12 feet each. One 

 of these panels is put down stationary, and four rafters 

 are put up over it, two at each end, to support the other 

 two panels, which, when open, are raised up and leaned 

 against the rafters toward each other and form a roof 

 over the lower or stationary panel. 



When the cover is open in this way two-thirds of the 

 cover is open, one-third is always closed. When closed 

 the two side panels are turned down until they lie flat 

 on the framework and the whole top of the shed is closed 

 snug. 



This plan gives the trees both sunshine and shade. 

 The openings in the cover, when open, run east and west. 

 The sun in passing over throws sunshine and also casts 

 a shadow upon the trees below in its day's journey. The 

 trees in this shed are doing well and now have a nice crop 

 of young oranges on them. I could give you numerous ex- 

 perience we have had with our sheds, but I understand
