on Loowechow (proposed further on) would lead Mercantile vessels through West Samma channel, and into Hong Kong roads.

The south-eastern part of the Great Ladrone island offers a good site where a light house would, probably be erected and maintained with the least expense; it is also a good weatherly position for vessels to make in the south-west monsoon. But I have often seen that island covered with clouds when smaller islands were quite free from them; nor is the position so favorable for leading vessels up to the Lammock channel, and would necessitate the light on Loowechow having a visible range of 20 miles to enable it to be seen before the light on the Great Ladrone was lost sight of.
The locality of the Mweitan rocks would be a good position for a light to vessels when approaching the land, as a light placed there, with a visible range of 20 miles, would be seen before a ship coming from the southward could get dangerously near any of the Hypony or Sema islands. It would also lead vessels safely through the Taitam channel.
