This latest move; an official Nature NS policy sounds like a move to m= uzzle discussion and replace it by worship of some ad-hoc form of Reli= gion.  If that in fact proves to be the case then Naturens will wither= to a bird watch forum or some dust on a cobweb. </div>=20 <div>   </div>=20 <div>     In one of my recent e-mails I indicated the merits o= f research into this and many other related questions.

Good soil or good highway fill too shallow to bother mini= ng ? </div>=20 <div>   </div>=20 <div>     For example, the large barren west of the Costley ho= mestead on Route 12 (just this side of the Salmontail River) was referred t= o by one of the Costleys (Milton or Truman) as "the fire barr= ens". It goes back to the mid-1800s if not earlier. And it seems likely= that these barrens had help getting and remaining in that state.
