The written history began when European navigators first sighted New Guinea in the early part of the 16th century.ollowing the passage of the Papua Act in 1905, British New Guinea became the Territory of Papua, and formal Australian administration began in 1906, although Papua remained under their control a British possession until the independence of Papua New Guinea in 1975. There was little economic activity in Papua.
Floor hole. An opening measuring less than 12 inches but more than 1 inch in its least dimension, in any floor, platform, pavement, or yard, through which materials but not persons may fall; such as a belt hole, pipe opening, or slot opening.
Standard Size. The waste pipe that fits through the hole in the floor is called a flange, and it has two parts: a pipe that connects to the waste line and a ring that gets bolted to the floor. The ring has slots for the bolts that hold the toilet down. The flange pipe can have a diameter of either 3 or 4 inches, depending on the size of the waste line, but a 4-inch hole works in both cases. Plumbers cut it with a hole saw or a reciprocating saw.
