Coding scheme for samples for IRG world-wide co-operative field experiment
Each sample has been given a number containing six digits (eg 16 23 05). The first 2 digits indicate the country and person supplying the timber, the second 2 digits indicate the species of timber, and the last two digits indicate the treating concentration. All samples which end with the numbers 26 to 50 are to be placed in one site in the United Kingdom, probably at the Imperial College site at Silwood. All the other samples will be returned to the persons in the following list according to the code number indicated.
