The Aurora and Zone feemed a great deal nearer 
one another in the Horizon than in the Top. If we could 
fuppofe this Difference to be entirely Optick, and thefe 
two Circles really Parallels, that would be enough to 
compute the Diftance of the Phsenomenon from the 
Earth. But the Suppofition, though it feemed, at firfl, 
pretty allowable, is by no means to be admitted ^ for 
it would follow, that the Phasnomenon was at leaft di- 
llant from us one twenty-fourth Part of the Diameter 
of the Earth, which is too great an Altitude to be 
believed. 
I have feen lately another Phasnomenon of a quite 
different Kind. A Friend of mine having caufed fome 
Pipes of Alh-tree Wood (that brought Water to his 
Fountain during at lead: twelve Years) to be taken out 
of the Earth, they were left in a Yard not paved, where 
tlifcy rotted alraoft entirely : But in their room 
there did ftioot forth from the Earth, a little Foreft of 
Afh-trees. They are now in a flour i(hingWay,and about 
3 or 4 Foot high. It is remarkable, that more than 
fifty young Trees are fprung up exadly where the Pipes 
had been laid, and no where elfe in the Yard. 
There is no A(h*tree there about, nor perhaps at a very 
great Diftance, the Yard being in the Town.
