the cottonwood leaf beetle (Lina scripta), though not to such 

 a degree as the poplars. The willow makes a denser shade than 

 cottonwood, but not so dense as box elder, which it only sur- 

 passes in hardiness. As a nurse tree box elder is to be prefer- 

 red. In this plat ash and elm were substituted it part for wal- 

 nut and birch. 



The poplar has not grown as well in this plat as in plat 6. 

 owing probably to the spreading roots of the willow. The box- 

 elder has done better, relatively, than any of the other species. 

 The general indications, however, are that this willow is not 

 suitable for mixing with other trees. 



SUMMAEY. This plat contains fifty elm trees, averaging 3J 

 feet, ten of which are over 6 ft. high, the tallest being 8 ft. 2in. ; 

 67 ash averaging 3ft. 8 in., three over 6 ft. high, the tallest being 

 6 ft., 4 in.; 35 cherry averaging 3 ft. 6 in., of which only one was 

 six ft; 24 birch, of which 7 were over 6 ft., the species not in as 

 good condition as in plat 8; 3 small walnuts; 235 red willow 

 averaging 5 ft. high, very few being as much as 7 ft. high, much 

 branched and bushy; 289 poplars, averaging 3J ft., not thrifty; 

 256 box elder, averaging 5 ft., the tallest being 9 ft. 10 in. 

 Total trees in plat 959.

This is the only plat in the plantation that is composed en- 

 tirely of hardwood trees. And while from the stand point of a 

 quick soil cover the mixture is not so useful as one in which a 

 rapid growing soft wood has been largely used, yet it is a ques- 

 tion whether the greater value of the thinnings will not more 

 than pay for added cultivation necessary. The plat has been 

 freer from weeds, after being two times cultivated this year, than
