In looking at the chart to see detail about the thread on the Balmoral Canal, I noticed that the canal is not seen because it is covered by an inset. So I looked at an old (1962) Public utilities chart. No inset, but no canal either.
Anyway, on the 1962 chart two islands are shown in the adjacent cove. A larger one named Lincoln and a smaller one with no name on the chart. On the Bizer chart, the larger island appears to be named "Birch" and the smaller one "Lincoln". Is this a change in names or is one of the charts incorrect?

So we have a Birch Island east of Bear Island (in Meredith?) and one in Moultonborough. Is that correct? When was the Moultonborough Birch Is named?

Sometimes, I think I would like to rename some of the Loon Islands and the (4?) Silver Lakes that are scattered around the state.
