diflinguifhable in the northern province of Ulfter; and chiefly in 

 the extreme counties of that province, where a northerly latitude, 

 joined to an expofed fituation on the coafts of the ocean, forms 

 an apt flation for obfervations, and exhibits, as it were on a mag- 

 nified fcale, the degrees of the phtenomena themfelves. 



Three natural regifters of thefe effeds have come within my 

 obfcrvation ; the trees of the country, the fands of the fea coaft, 

 and the tides of the ocean : Of each of thefe I fhall make mention 

 in its order. 



Of the Trees. 



It is a fad extremely well eftablifhed, that the pine tree, and 

 peculiarly that fpecies vulgarly denominated the Scotch fir, 

 formerly grew on many of the mountains of this kingdom, and 

 on parts of the northern and weftern coafts, exceedingly bare 

 and open to ftorms. Vaft roots, and noble trunks of this fpecies 

 of pine have been feen and examined by me with attention, 

 in fituations where human induftry cannot now rear a twig of 

 the hardieft tree. On the higheft lands of the general furface of 

 the kingdom, in the county of Weftmeath, amid the mountains 

 of the county of Antrim, and on the naked coafts of Enifhowen, 

 and Rofles, in the county of Donegal, pine trees have formerly 

 arrived at an age of an hundred and twenty years, have grown 

 to the fize of a yard in diameter, and furpaffed fifty feet in 

 height.
