similar data for the foro:st-tr<^e tuid evergreen nurseries, and the seed- 

 ling forest-tree plat; physical analyses of the soil of the experimental 

 l)lats; observations on the root growth of trans])lanted trees; notes ou 

 the insect enemies of forest-trees in the State ; and a discussion of the 

 value of a dense leaf canopy. This bulletin is a report of progress in 

 lines of work previously recorded in Bulletins Nos. 12 and 15 of the 

 station (See Experiment Station llecord, Vol. I, pp. 20 and 315). The 

 soil of the station i)lantation is a black mixture of sand, clay, and 

 organic matter underlaid by clay. Observations indicate that the 

 roots of forest-trees are able to penetrate the clay subsoil. 



The cotton-wood leaf beetle {Lina scripta), elm snw-Qy [Cimbex anier- 

 icana), emperor moth {Platysamia cecropia), lilac borer {^i]geria syringce)^ 

 and the box-elder twig borer were especially troublesome in 1890. 



From observation and information the author regards the following 

 species as especially valuable for forest plantations in South Dakota: 



Quick-growing, dense-shading trees. — Box-elder {Neguiido aceroides), silver iiiai)Ie (Acer 

 dasiicfuytim). 



Slower-growing, more valuable trees. — Ash (Fraxinus viridis aud F. americana) white 

 elm ( Ulmus americana), black wild cherry (Prunus nerolina); and for deep soils in the 

 southern iiart of the State, black walnut (Jiiglans nigra) and butternut (J. cinerea). 



South Dakota Station, Bulletin No. 21, February, 1891 (pp. 16). 



Small geain, L. Fostek, M. S. A. (pp. 03-70). — This includes 

 accounts of experiments with wheat, rye, oats, and barley, in continua- 

 tion of those reported in Bulletins Nos. 11 and 17 of the station (See 

 Experiment Station Record, Vol. I, p. 19, and Vol. II, p. 132). The 

 experimental plats were on a sandy loam upland, and were each one 

 ei.Thth acre in extent. The spring was very dry, and the hot winds of 

 July severely damaged the crop. 



Wheat. — Tabulated notes are given on 17 varieties, and brief descrip- 

 tive notes on Lost Nation, which does well in the region of the station, 

 and Ladoga, which in a three-seasons' test, has not proved satisfactory. 

 There are also brief accounts of experiments in methods of seeding, 

 cultivation, and top dressing. Experiments with varieties of winter 

 wheat indicated that while these varieties were not winter-killed they 

 could not endure the dry weather of the spring. 



^yinte7• rye. — Two varieties. Excelsior and a small common rye, were 

 grown alongside the winter wheat and endured the drought well, yi(;lding 

 24 bushels per acre. Experience in this section for the ])ast 10 years 

 indicates that winter rye may be successfully and profitably grown 

 there. 



Oats. — Tabulated notes are given for 25 varieties. White Bonanza, 

 American Banner, Wide Awake, Black Tartarian, Dakota Gray, and 

 White Suri)rise were deemed worthy of especial mention. 



Barley. — Tabulated notes are given for 10 varieties.
