statistic.11 This was important since statistical procedures for calculating parameters like probability and heritability are based on statistics of the normal distribution. Before leaving Canberra I wrote program CORRE to compute product-moment coefficients between pairs of variables, WEIGHT CORRE to compute weighted disk values and weighted whole tree values and produce a correlation matrix of all combinations of disk values against whole tree values, ARITH CORRE a similar program to the former except for application to arithmetic average values, WEIGHT CORREG similar to WEIGHT CORRE except that an optional regression analysis subroutine was available, and ARITH CORREG similar to ARITH CORRE except that an optional regression analysis subroutine was available.12

We left Canberra at 5.20 PM on Wednesday 3 April 1968 and spent the night in Sydney. After an early start we left Sydney Airport at 7.00 AM and, via a brief stop in Brisbane, arrived in Port Moresby at 12.00 noon on Thursday 4 April 1968. This was on one of the first round-trip daily daytime flights to operate between Sydney and Port Moresby and serviced by a TAA Boeing 727 (right).

We were accommodated overnight in the Hotel Papua. From 8.00 AM to 11.30 AM the next day Friday 5 April I spent in a briefing session with Alan Cameron and Kevin White at the Department of Forests Headquarters in Konedobu. Then Kevin invited us to have an early lunch with him at the Hotel Papua, before a rush to the airport to depart at 1.30 PM via Lae for Rabaul, where we arrived at 5 PM. We were met and taken by road to Keravat, arriving home at 6 PM. From 7.45 AM on Monday 8 April 1968 we were back at work in our respective offices.

It took nearly two days to inspect the nursery, bring the cuttings equipment back into service, attend to a pile of correspondence and fill in the compulsory blue FD9s and green boot allowance13 forms.

11 In statistics, the Kolmogorov–Smirnov test is a nonparametric test of the equality of continuous, one-dimensional probability distributions that can be used to compare a sample with a reference probability distribution, or to compare two samples. It is named after Andrey Kolmogorov and Nikolai Smirnov. 12 Appendix 5, pages 262 and 263 In Davidson J 1972 loc. cit. 13 The FD9 was a monthly diary with two lines (AM and PM) for each day of the month where an officer filled in the one or two major activities that he had undertaken. The boot allowance form was a monthly form in which field officers (Forestry Officers, Patrol Officers, Agricultural Officers and the like) recorded the number of miles walked each day. The miles earned money to be paid to the officer to buy 57
