34、he surface area of the specimens.TABLE 2 Design Numbers of Poultry and Garden Fence (Furnished in 10-rod Rolls)NOTE 1Design Numbers: In accordance with trade practice, each design of fence is expressed by a group of three numbers separated by a dash (-).The first number of the group contains either
35、three or four digits. In a number containing four digits, the first two represent the number of horizontal wires;and the second two the total height in inches. Where three digits are used, the first one represents the number of horizontal wires, and the remaining twothe height in inches. The second
36、number of the group indicates the spacing of the stay (vertical) wires, in inches. The third number of the group indicatesthe gauge of the intermediate line (horizontal) wires and of the stay wires. It does not apply to the top and bottom horizontal wires, the gauge for whichis shown separately in t
