368 CITRUS FRUITS AND THEIR CULTURE. 



costs but 25 cents per hour, and one man can keep from 

 twenty to forty fires going. When the shed is closed the 

 temperature is from four to ten degrees higher without 

 any fires than it is outside. In the winter when the trees 

 are dormant, I build fires between twenty-eight and 

 twenty-nine degrees, but in the early spring, when the 

 trees begin to grow, I "fire" up at thirty-two degrees. 

 My shed covers about two and one-half acres, and during 

 a freeze when the temperature outside fell to 17 1-2 de- 

 grees, I kept the temperature between 31 and 34 degrees 

 without any trouble and had only ten fires, burning not 

 more than one-quarter of a cord of wood in nine hours 

 and a half. 



Some people think that trees will not bear under a 

 shed, but it is a mistake. My trees bore well in the spring 

 of 1902, and I fertilized them last fall for fruit, and this 

 spring they are bearing as heavily as they can. My trees 

 look fine and are free from disease. The shed is a wood- 

 top one, and opens and shuts by means of doors thirty- 

 two inches by seven feet, which are fastened to stationary 

 walk-ways twenty-eight inches wide. Two rows of doors 

 are fastened to one walk-way and constitute little more 

 than two-thirds of the top. The doors are fastened by 

 means of wire loops hooked over nails, and can be readily 

 taken down. Part of the sides of my shed are made of 

 veneer panels four feet wide and part of one-inch boards. 

 The panels and boards are set in racks so they can be 

 readily taken down and put up without nails. In my 

 opinion, the panels are far superior to the boards, as they 

 make a tighter wall and are much easier and quicker 

 handled. The cost of taking down the sides and doors and 

 putting them up again is about f 40 per year. F. Swift.
