grow in America, but we have many others which will answer 
the same purpose.* 
The third step is the planting of pines. 
The fourth step, and the ideal stage, as far as the fertility of 
the soil is concerned, is the production of a rich, dense forest of 
the broad-leaved trees, such as the Forest of Compiegne, which 
is pictured in the frontispiece of this report. 
Forestry in Denmark. 
Nowhere in Europe is forestry more intensively developed 
than in Denmark. ‘These practical people waste no time in 
advertising what they have accomplished. They have been 
working more for financial gain than for glory. There is a 
commendable lack of sophistry and impractical notions in refer- 
ence to their forest management. It is not my intention to 
attempt to describe their methods in this connection, but no 
place -is more worthy a visit by American foresters. For many 
years these enterprising people have been at work developing a 
system of their own. They have been practically unnoticed by 
foresters until recently, when their methods were described by 
Dr. Metzger, in the Miindner Hefte. Several writers on the 
continent are endeavoring to show that the Danish system is. 
after all old, and has been elsewhere in practice more or less for 
some time. Even if this may be so, the Danes were the first to. 
fully appreciate its advantages and put it into execution. They 
have been quietly “sawing wood” while their neighbors have 
been holding learned discussions. The Danish foresters long 
ago traveled throughout Europe, absorbed what they needed 
and evolved from it a system of their own, adapted to the pecu- 
liar conditions of their little country. They were particularly 
influenced by what they saw on some private estates in England. 
They show, indeed, the same amount of intelligence in every- 
thing they attempt. Their dairy industry is a model, every 
man and woman can read and write, and every traveler to their 
* The sandy soils of the Pines are in need of humus and green manuring. For this purpose there is 
no better crop than Lupinus perennis which will grow where other leguminous crops fail. The plants 
of this genus were named /ufinus from Lusus, a wolf, because it was thought that they devoured the 
fertility of the soil. Nothing could be farther from the truth, The serennial lupine of Southern New: 
Jersey is one of those pioneer plants which in the midst of the sand is paving the way for less hardy- 
species,
