of the proposed fence, so that in many instances posts can be 

 dispensed with by stringing the wire on trees. Of course the 

 trees would not be at regular distances in all cases ; but by 

 having posts every six, eight, or even ten rods, the inter*- 

 vening supports can be made of stakes which can be driven, 

 with the help of a bar to make the holes, at a comparatively 

 trifling cost, and the material can be gotten from the trees 

 as you go along. I have therefore made a calculation here, 

 leaving out the posts and the cost of setting the posts, so that 

 persons having pastures situated in the way I have described 

 may reduce the necessary cost of fencing very considerably. 

 My calculations are as follows : — 



To fence a square lot of 20 acres, six wires (226 rods), posts, $99.44 



Cost per acre, 4.97 



With five wires and posts, 88.14 



Cost per acre, 4.41
