""" Rainfall In the area of these strip was carefully checked against rainfall rain-fall In surrounding untreed areas. The results were astonishing. The increase In rainfall In the area bordered bor-dered by the forest strips was from? 13 per cent to 27.2 per cent In the-treed the-treed areas the evaporation between) the strips was from 20 to 35 per cent less than In the open. |
