Capitolo 24

the difficulty to maintain a great boat pushed by mechanic
you motorize, or you sail, sufficiently near the craft to assist the
observatories, prevent its use, and the better result will be
gotten assuming a substantial row boat, fit to the navigation with
a wide ray. The boatmen appreciate the inclusion of a tree,
sails, and very of sea ballasts in the equipment to facilitate
their house of return when the job of the day is done what you/he/she can happen
eight or nine miles street, with fast of twilight that passes in
obscurity. Two boatmen or a man and a strong should be us
youth.

In to work with theodolites, it is as before well to start to
stations of observation choices to intervals along the coast, walked
pegs in the earth so that they can be found later easily,
and it mends their position on a 1/2500 artillery map in the usual one
way. However you/he/she can be found in practice, that later
a station that goes away is not possible to arrive the next one
before the time arrives for another sight to be taken. In this
case the theodolites must have put on on magnetic north to a
intermediary position, and seen taken to at least two
miliary stones, the positions of what you/he/she has shown on the map and the
point of observation drew accordingly as neighbor as possible
from the use of these readings. Since the sights will be
taken by points on the edge of the beach that is of
course, shown on the map it is possible, after having put above to
northerly magnetic, to mend the position with approximate accuracy
from a sight to a miliary stone only, but this should be only done
in unusual circumstances.

The method to take the observations with two theodoliteses, as
adopted by the writer, you/he/she can be explained better by a reference to
Fig tree. 9 that they represent a piece reentered of the coast. The
end of the maritime outfall and proposed it provides of sewers from that the point the
observations would naturally start, 1 are marked the numerals,
2, 3 4, etc. what they point out the positions of the craft as
observed at times. A lot of intermediary observations
