THE MIXED FOREST PLATS. 



The following notes on the ten oldest forest plats, which were 

 planted with one and two yea v seedlings in the spring of 1889, 

 are given as showing the present condition of the various mix- 

 tures, and their utility in shading the ground. The plats are 

 numbered as indicated in the diagram published. 



PLAT NO. 1. 



This plat, as will be seen by the diagram, has for its tempo- 

 rary trees (those that are to be taken out first as thinning be- 

 comes necessary) box elder and Populus certinensis, and for 

 its permanent trees green ash, white spruce from Black Hills 

 and Scotch pine. The spruce were used, not because they were 

 regarded as especially suitable for permanents, but because, 

 having but few specimens, it was thought they would have a 

 better chance in this arrangement to show how w r ell they would 

 withstand exposure. The following diagram shows the position 

 of the trees, which are four feet apart both ways.
