birds and to guard against this the seed should ke coated with red 
lead before being sown. Again, wind will blow away some of the 
seed and in other cases will cover the seed too deeply with sand. 
It is certain that the action of the wind will be greatly reduced 
by the littoral dune and the forest, but just how efficient this shel- 
ter will be can be determined only by actual experiment. 
It is obvious that if the sweep of the wind over the area in the 
lee of the dune is not reduced to a minimum, the success of plant- 
ing by direct sowing without previous preparation of the site will 
be impossible. In such a case the surface of the area to be planted 
must be covered with a light covering of brush, laid in rows par- 
allel to the barrier dune. Seed should then be sown at the same 
rate as above among the brush. 
Such a method, although more expensive than the first plan, 
will insure success. The brush should be allowed to remain until 
the young trees are established and the year following the sowing 
it should be removed in order not to interfere with the growth of 
the seedlings. 
Brush can be obtained from the nearby forest. Myrtle, red 
bay, yaupon, or any similar material may be used. Brush cut 
from the tops and limbs of conifers after lumbering will serve 
admirably. Such material may be obtaided from recently cut- 
over areas in the forest. 
The forest immediately in the lee of the sands, the purchase of 
which has been recommended above, should be carefully conserved. 
Absolutely no cutting should be permitted until the dune forest is 
firmly established. 
The expense of fixing the sands can be only approximated. 
There was no opportunity in the limited time available to deter- 
mine the rapidity at which the barrier dune would accumulate. 
It is obvious therefore that the cost of the dune cannot be deter- 
mined, since it will vary directly with the the length of time 
which will elapse before it assumes permanent form. The cost of 
forestation can, however, be approximated, and will vary from 
$25 tn $40 per acre, depending upon the method. Seed of the 
loblolly pine are quoted in the market at $2 per pound but could 
undoubtedly be secured by contract at a much lower figure.
