How to start on my adventure—how to become a forester—was not so simple. There were no schools of Forestry in America. ... Whoever turned his mind toward Forestry in those days thought little about the forest itself and more about its influences, and about its influence on rainfall first of all. So I took a course in meteorology, which has to do with weather and climate. and another in botany, which has to do with the vegetable kingdom—trees are unquestionably vegetable. And another in geology, for forests grow out of the earth. Also I took a course in astronomy, for it is the sun which makes trees grow. All of which is as it should be, because science underlies the forester's knowledge of the woods. So far I was headed right. But as for Forestry itself, there wasn't even a suspicion of it at Yale. The time for teaching Forestry as a profession was years away.

I had no more conception of what it meant to be a forester than the man in the moon. ... But at least a forester worked in the woods and with the woods - and I loved the woods and everything about them.
Gifford's thoughts, when upon entering Yale (1885) his father asked 'How would you like to be a forester?'

If a man walked in the woods for love of them half of each day, he is in danger of being regarded as a loafer, but if he spends his whole day as a speculator shearing of those woods and making earth bald before her time, he is estimated as an industrious and enterprising citizen—as if a town had no interest in forests but to cut them down.

What do we plant when we plant the tree?
We plant the ship, which will cross the sea.
We plant the mast to carry the sails;
We plant the planks to withstand the gales—
The keel, the keelson, and beam and knee;
We plant the ship when we plant the tree.

What do we plant when we plant the tree?
We plant the houses for you and me.
We plant the rafters, the shingles, the floors,
We plant the studding, the lath, the doors,
The beams and siding, all parts that be;
We plant the house when we plant the tree.

What do we plant when we plant the tree?
A thousand things that we daily see;
We plant the spire that out-towers the crag,
We plant the staff for our country's flag,
We plant the shade, from the hot sun free;
We plant all these when we plant the tree.

When I came home not a single acre of Government, state, or private timberland was under systematic forest management anywhere on the most richly timbered of all continents. ... When the Gay Nineties began, the common word for our forests was 'inexhaustible.' To waste timber was a virtue and not a crime. There would always be plenty of timber. ... The lumbermen ... regarded forest devastation as normal and second growth as a delusion of fools. ... And as for sustained yield, no such idea had ever entered their heads. The few friends the forest had were spoken of, when they were spoken of at all, as impractical theorists, fanatics, or 'denudatics,' more or less touched in the head. What talk there was about forest protection was no more to the average American that the buzzing of a mosquito, and just about as irritating.
