The forest from which man takes his timber is the tallest and most impressive plant community on earth. In terms of man"s 11 life it appears permanent and unchanging, save for the seasonal growth and fall of the leaves, but to foresters it represents the climax of a long succession of events.
No wooded landscape we see today has been forest for all time. Plants have minimum requirements for temperature and 12 and, in ages past, virtually every part of earth"s surface has at some time been either too dry or too cold for plants to survive. However, as soon as climatic conditions change in favor of plant life, a(n) 13 sequence of changes occurs, called a primary succession.
First to colonize the 14 lands are the lowly lichens, surviving on bare rock. Slowly, the acids produced by these organisms crack the rock surface, plant debris 15 , and mosses establish a shallow roothold. Ferns may follow and, with short grasses and shrubs, gradually form a covering of plant life. Roots probe even deeper into the developing soil and eventually large shrubs give way to the first trees. These grow rapidly, cutting off sunlight from the smaller plants, and soon establish complete domination closing their ranks and forming a climax community which may 16 for thousands of years.
Yet even this community is not everlasting. Fire may destroy it outright and settlers may cut it down to gain land for 17 or cultivation. If the land is then abandoned, a(n) 18 succession will take over, developing much faster on the more hospitable soil. Shrubs and trees are among the early invaders, their seeds carried by the wind, by birds and 19 in the coats of mammals.
For as long as it stands and thrives, the forest is a vast 20 , storing energy and many elements essential for life.

Most worthwhile careers require some kind of specialized training. Ideally, the choice of an occupation should be made even before the choice of a curriculum in high school.

Unfortunately many young people have to make career plans without the benefit of help from a 24 vocational counselor or psychologist. Knowing little about the occupational world, or themselves for that matter, they choose their lifework on a hit-or-miss basis. Some 25 from job to job. Others stick to work in which they are unhappy and 26 they are not fitted.
One common mistake is choosing an occupation for its real or imagined prestige. Too many high-school students—or their parents for them—choose the professional field, 27 both the relatively small proportion of workers in the professions and the extremely high educational and personal 28 . The imagined or real prestige of a profession or a "white-collar" job is no good reason for choosing it as life"s work. 29 , these occupations are not always well paid. Since a large proportion of jobs are in mechanical and manual work, the majority of young people should give serious consideration to these fields.
Before making an occupational choice, a person should have a general idea of what he wants out of life and how hard he is willing to work to get it.

Most worthwhile careers require some kind of specialized training. Ideally, the choice of an occupation should be made even before the choice of a curriculum in high school. Actually, most people make several job choices during their working lives, partly because of economic and industrial changes and partly to improve their position. The "one 21 job" does not exist. Young people should 22 enter a broad 23 training program that will fit them for a field of work rather than for a single job.
Unfortunately many young people have to make career plans without the benefit of help from a 24 vocational counselor or psychologist. Knowing little about the occupational world, or themselves for that matter, they choose their lifework on a hit-or-miss basis. Some 25 from job to job. Others stick to work in which they are unhappy and 26 they are not fitted.
One common mistake is choosing an occupation for its real or imagined prestige. Too many high-school students—or their parents for them—choose the professional field, 27 both the relatively small proportion of workers in the professions and the extremely high educational and personal 28 . The imagined or real prestige of a profession or a "white-collar" job is no good reason for choosing it as life"s work. 29 , these occupations are not always well paid. Since a large proportion of jobs are in mechanical and manual work, the majority of young people should give serious consideration to these fields.
Before making an occupational choice, a person should have a general idea of what he wants out of life and how hard he is willing to work to get it. Some people desire social prestige, others intellectual satisfaction. Some want security; others are willing to take 30 for financial gain. Each occupational choice has its demands as well as its
