If the light were placed on Gamtoo island, it would not be so useful for clearing the Nine-pins, nor so convenient for vessels to lie to off.
Cowhow light.
I would propose placing a flashing light, visible 12 miles, on the island of Cowechow. This island affords an excellent position for a light which would conduct us through both Suma channels and into Hong Kong roads. No other position would answer that purpose.
Note. I recommend the light on Waglan being revolving, that on Cowechow flashing, to readily distinguish them from the bright lights of the fishing boats.
