Doing the mam stream and pacmg the tributaries, I located all the permanent and in- termittent streams that flowed over the lowest land contaimng all the wet spots that markedly influenced growth or gave trouble with roads. I also sketched m the drainage pattern on which the higher land was hung. With the valleys done, it was easy for me to locate the ridges and knolls and to note which were steep and which gentle.

This part was probably a farm lane that old man Stratton had laid out to get to what one of the deeds calls the "long mowing." In the early days wet swales were cleared and used to cut hay from the natural grasses that took over once the sprouts were killed off. The road continued on but gradually became more overgrown and dif- fuse, so that it looked hke a skid road used occa- sionally for logging. Judging from the old pines lying across it, which probably had blown down in the hurricane of 1938, this part of the road had been abandoned for over 40 years. Finally, even this trace disappeared some distance short of the back boundary. Primitive as it was, the old road Oaks tend to occupy the dry ndge tops.

Mapping Tree Cover With the topography roughly filled in, I had also defined the main growing sites with moisture regimes different enough to be reflected in the growth of the trees. The wet swales were domi- nated by red maple, while, at the other extreme, the dry ridge tops were given over to oak. The slopes between had mixtures of hardwood with a pine here and there, while some of the gentlest slopes with diffuse, mtermittent streams had a lot of hemlock under the hardwoods.

Of course, I knew the local trees because of my traming, but many owners must start from scratch and learn to identify the different species.
