A wave of the tide will cross the open sea in a right line, but
as it passes nearbyer along the coast the progress of the line
the beach he delays while the part of continuous centre to the
same speed, so that on plain the wave supposes a convex form
and the branch waves reaching the form of beach an acute angle
with the coast line.

CURRENT OBSERVATIONS.


There is considerable difference in the sketch of crafts
assumed in current observations, dependant to of the extension on
if you/he/she is desired to verify the direction of the surface
motion or of a deep tide, it doesn't serve as some means follows
what they races in simultaneous directions. There is also
sometimes the considerable difference in the speed of the
depth tide different--the tide of surface that is more
susceptible to influence of wind. A good form of deep craft is
seen in Fig tree. 8. It consists of a rod 2 in within 2 in, or 4 sqs in
The lowest end of what a wood box and cable approximately 6 in within 6 in
it is sheltered in that pebbles have put for overcoming the
the buoyancy of the craft and it provokes him/it to take and to maintain a
right position in the water with a length of 9in of the rod
statement above of the surface. A small hole is formed in the top of
the box for the insertion the pebbles with which are stopped on
a cork when the craft is repaired. The length of the wish of rod
various second water's depth, but generally it will be
you find convenient to approximately assume a craft 10 fts and possession a
you approximately save 6 fts a depth, but otherwise it is similar in everybody
respects, for use in a little deep water. A convenient craft for gauging
the motion of surface can be served as a bottle of champagne it voids
him gotten heavy with stones and partly he/she filled with water. The top 12
in of rods and the rope and neck of the bottle, as it is able the case
both, you/he/she should be painted red, as it makes this colour it is floating more
