Next place a stake along the side of the lake at a point D. Then in a similar manner measure the triangle with the transit.  With the protractor the lines ad and BD can be plotted on the plan.  With the scale the length of the lines ad and BD can be estimated from the map.  The rest of the lake is surveyed in the same manner.  It is only necessary to take other points on the lake and survey the resulting triangles.  It is a good idea to use four-foot stakes with flags placed so as to be easy to sight to them.

Finally a tracing may be made with carbon paper giving only the shore line and leaving out the lines of the triangles and the map is finished.  The boys in one camp surveyed a lake a mile long with home-made instruments with excellent results.

Boys should be taught how to use the compass and a map in tracing their way through an unknown country.  Also to travel by the stars or by the moss on the trees.

Experience only can determine what should be taken to camp.  Usually the first camping trip decides what to take on the second trip, and also reveals how few things, providing they are right things, one really needs to be comfortable in camp.  A boy’s mother, who is generally the official trunk packer of the family, makes a mistake in stowing away in the trunk a lot of things not serviceable or suitable for camping.  Cotton goods, except towels, handkerchiefs, and hose, are of no use.  Gray woolen shirts, gray, brown, or green sweaters (a boon to campers—­avoid white, red, or striped colors), khaki suit, outing flannel pajamas (tan color preferred) are in the class of real camp necessities so far as clothing is concerned.  The hat should be drab or khaki color, of campaign style, something that will shed water and sun.  The hat used by the Boy Scouts of America is admirably adapted for campers.

The outfit may be divided into four classes:  things necessary, things desirable, things convenient, and luxuries.  Boys who go camping for two weeks or less should take articles in the following list marked (1); those who go for four weeks or less should take articles marked (2) in addition to those marked (1); and those who go for what may be called the season, six or more weeks, should take those marked (3), in addition to all of (1) and (2).
