while the moon does her actual course in 

 twenty-eight days. When the sun and moon 

 have changed their relative positions so that 

 they are at right angles to each other with 

 reference to the earth at a quarter-circle 

 apart the sun and moon will be pulling 

 against each other; at least this is the point 

 where the moon is at the greatest disadvantage 

 with reference to its ability to attract the 

 water. 



Because one-quarter around the earth the 

 sun is creating his own tide, which to that ex- 

 tent counteracts the effect produced by the 

 moon, the tide under the moon at this point is 

 at its lowest point and is called the " neap " 

 tide. When the moon has passed on around 

 the earth to a point where it is opposite to 

 that of the sun at a half -circle apart there 

 will be another spring tide, and then another 

 neap tide when it is on the last quarter, and 

 from that point the tide will increase daily 

 until it reaches the point where the sun and 

 moon are in exact line with reference to the 

 earth's center, when another spring tide 

 occurs. From this it will be seen that there 

 are two spring tides and two neap tides in each 

 twenty-eight days. This is the fundamental 

 law governing tides. 



There are many other conditions that 

 modify tidal effects. Neither the sun nor the 

 moon is always at the same distance from the
