THE TIDES.

To the Editok of the Evening Mail* Silt.— Thanks to you for inserting nij former letter re tides, and also to your Mr "T S." for infoimalion about them. As fhe lunar tides are so much higher, in theoi y lhan the solar tides, how is it thai in practice the solar tides during the maimer are invariably the higher of the two, night tides be ng many tect lower during full and change (Spiing tides' than daj tides? I understand that fit sen, away from the ii.fluenceof land, not any cuueut has ever bt'cu obseived that can iv au\ way be tiaced to the ii lluence of eithei the sun or moon, as the sun aud moon have such an attractive i.lluence on the Aater, wou d there not be almost a tidal wave fo lowing each from East to West '! New Zealand is only a loLg narrow strip of land, and ihoie is not any land to the East to affect the influence of tbe moon tr sun on the sea, and why is it that the Bmfl tide is live houis earlier than it is at Cape Campbell which is about six degrees East, and consequently ought to have the tide Brst, if the water were following the moon, which it does in theory ? I unde - stand that the influence of the moon is actually e_erted oa the water (sea) about two or t'ireo hours after passing over the meridian. Where lam sitting now, it w_s high water to-day about 9.0 pm. (May 9th) and ihe moon was over the meridiun about 11 p.m. According to theory high tide ought to be at about 1-30 a in. tomorrow or iv other words, when tbe moon haslhegieatist inllueuce in theo-y-loi drawing the water up. The tide has re ceded four hour?, and it v getting on towards low water. Why is this. I am &c. Senex Homo.
