Growing and Planting Hardwood Seedlings.

1 The slower growth in each case is on poor situations; the more rapid growth, on better situations. Where 

 only one figure is shown, it represents approximately the average growth on all situations where measure- 

 ments have been recorded. In plantations, the height growth should equal and often exceed the faster 

 rate of growth indicated by the table. 



2 Growth in plantations on farm lands. 



3 Measurements made on trees in the lower Mississippi Valley where growth is very rapid. 



PLANTING TWO OR MORE KINDS OF TREES TOGETHER. 



A mixture of two or more kinds of trees in a plantation may some- 

 times he desirable, although it is not ordinarily recommended. For 

 their best development, some trees, such as cottonwood, should be 

 spaced widely in a plantation; others, such as black walnut and 

 black locust, have such scant foliage that their shade does not 

 prevent the growth of a heavy sod of grass. In both of these cases, 

 a mixture will more completely utilize the area planted, increasing 

 the yield and bringing about better forest conditions in the plantation. 



Mixtures may be desirable for other reasons. Planting stock of 

 one species alone may be expensive; and if a less valuable tree, or 

 filler, to be cut out when the trees begin to crowd, is mixed with the 

 main crop, it will keep down the first cost. If a species to be planted 

 is liable to serious diseases or insect attack, as are chestnut and black 

 locust, the planting in mixture with another kind of tree not liable 

 to such attack will provide for a stand of trees in case the chestnut 

 or locust is killed. 



The following list gives a number of hardwood mixtures which 

 should prove successful on soils and in regions adapted to both 

 species. It can not be stated with assurance that these mixtures 

 will produce a satisfactory stand, because experience with them has
