1. Steering compass in box.

2. Binnacle lamp.

3. Port through which helmsman sees the compass; this opens to the left.

8. Reflector, by means of which the master, when at the chart table, can see the lubber line, thus making the steering compass a "tell-tale." (Common lookingglass will answer for the reflectors in 6 and 8.)

Coastal navigation; or, Notes on the use of charts

NOTE.

In working out the examples given in this book the following articles are required, viz.: one pair of 18-in. parallel rulers, one pair of dividers or compasses, another pair with a socket for a pencil in one leg (those made of nickel with steel points are the best), one H or HH pencil, and a piece of indiarubber.

In unfolding the chart in this pocket notice the creases, so that you may be able to fold it up again as it was folded at first. Should you not wish to fold it again you can mount it as follows (but you cannot fold it after it has been mounted; then, however, you can roll it) :

Stretch a piece of brown holland, or similar material, about an inch larger all round than the chart, by tacking it down upon as even a wooden surface as you can find. A deal table will answer the purpose, and the tacks should not be more than 4 inches apart. Prepare half a cupful of stiff but smooth flour paste, thoroughly wet the holland with water, then cover it all over with paste. Now damp the back of the chart and lay it on the holland as evenly as possible. With a sponge or pad of soft rag or tow press down the chart, commencing from the middle and working towards the sides. Take care not to stretch the chart unevenly, as you are liable to do by pressing too hard. Leave it in a dry place for twenty-four hours, then take out the tacks, cut off the holland, leaving an edge of half inch all round; rub a little paste on this edge and turn it down on the margin of the chart. Give time to dry, and your chart will be strongly mounted.
