538 CITRUS FRUITS AND THEIR CULTURE. 



" Sheet tents are made either in a regular or in an 

 oval hexagon, and perfectly flat. A pair of rings is often 

 attached on each side, near what is intended as the front 

 edge; it is convenient to attach these rings by iron links, 

 so that they can be rattled and found in the dark by shak- 

 ing the tent. 



The movement of the tent is accomplished by the use 

 of two poles. These are usually simple poles with a small 

 rod projecting from the upper end, over which the ring 

 of the tent is slipped, a rope is also fastened at the upper 

 end. The length of the pole is slightly greater than the 

 height of the trees it is desired to cover. Sometimes the 

 pole has the same shape as the lifter used for the box 

 tents, but the pulleys and guy-ropes are not needed, ex- 

 cept for the largest trees. 



********* The men approach the tent to be 

 moved, poles in hand, and finding the rings insert the small 

 rods at the end of the poles and take a hitch with the rope 

 over the ring to prevent the latter from slipping off. They 

 then proceed to the other end of their poles, which they 

 have placed even with the trunk on opposite sides of the 

 tree to which the tent is to go. While taking this station 

 they have not let go of the rope, but have held it tight 

 enough not to loosen the tent ring. The next step in the 

 process is to place one foot on the end of the pole, to pre- 

 vent it from slipping, and to pull on the rope. This will 

 lift up the edge of the tent ****** As 

 the men continue to pull on the rope the end attached to 

 the tent moves through the arc indicated by the line of 

 arrows. As soon as the pole becomes nearly enough up- 

 right, as not to slip when the foot is removed from the end 

 the man backs off, away from the tree, and thus gets a 

 more direct pull on the tent which by this time has begun
