During the past two decades the practice of forest tree 

 planting has established itself in America. Twenty years 

 ago very few forest trees were being planted. Now they 

 are being set out by the millions.and many thanks are due 

 the good judgment of the foresters who have placed white 

 pine at the head of the list. The growth and the ultimate 

 significance of the practice of forest tree planting may 

 be appreciated by studying the following table which gives 

 the number of white pine trees planted on the State For- 

 ests of Pennsylvania from 1902 to 1919 inclusive:

At first it may 

 seem incredible that 

 more than 20 mil- 

 lion white pine 

 trees have been 

 planted in 18 years 

 on the State For- 

 ests of Pennsylva- 

 nia; that is, an av- 

 erage of more than 

 one million per 

 year. This does 

 not represent the 

 total planting for 

 other kinds of 

 trees have also been 

 set out on many 

 idle acres of State 

 Forest land. In r.d- 

 dition to the State 

 Forest planting at 

 least 10 million 

 white pine trees 

 have been planted 

 by private owners 

 of forest land in Pennsylvania. Most of the planting 

 stock was supplied by the Pennsylvania Department of 

 Forestry. And in other states, particularly New York, 

 Massachusetts and Connecticut, many million young 

 white pine trees have been planted on barren waste land 

 Many of the trees comprising the older plantations h;n-- 

 already reached a size of 20 to 30 feet in height. The 

 growth during the first few years is rather slow, but 

 each successive year it becomes greater until the annual 

 height growth reaches two to three feet, and in excep- 

 tional cases it may be as high as four feet in a single sea- 

 son. The following table will give the height growth of 

 an ordinary plantation during the first 10 years after its 

 establishment :

Many of these planted baby trees were set out by school 

 boys and girls. The Boy Scouts have taken an active part 

 in the tree planting work wherever it has been called to 

 their attention. Tree planting by boys and girls should 

 be encouraged everywhere. It is a pleasant pastime, and 

 also a useful and helpful practice.
