samples for analyses are not drawn until the fertilizers are in the Ijunds 

 of local agents. Owing to the lateness of shipments into the State 

 during- the present season this plan has delayed somewhat the publi- 

 cation of analyses, but is still considered preferable to accepting sam- 

 ples sent by manufacturers. The bulletin contains analyses and valu- 

 ations of thirty-seven fertilizers and a revised list of all brands licensed 

 for sale in the State. Former valuations of the station have aimed to 

 represent approximately the cash cost at retail of the mixed fertilizers 

 at the seaboard ; but for the present season the " commercial value" of 

 a fertilizer is reckoned from the actual retail cash price of the ingredi- 

 ents in bags at the seaboard^ including no expenses of mixing or hand- 

 ling. For interior points freights must be added. By this system the 

 valuation for available phosphoric acid and potash for the season of 

 1890 will be 5 cents each, and for ammonia 13 cents per pound. This 

 system of valuation has been adopted by North Carolina, Virginia, and 

 South Carolina.

Experiments with potatoes, W. J. Green (pp. 5-14). — 

 Tests of varieties (pp. 5-11). — A tabular record is given for 48 varie- 

 ties grown at the station in 1889, for 13 varieties grown by W. Dres- 

 bach, of Pickaway County, and for 8 varieties grown by B. H. Brown, 

 of Butler County, F. Patton, of Harrison County, andM.E. Eidmiller, 

 of Miami County. The results vary sufficiently to indicate that general 

 conclusions can not be safely drawn from tests made in a single locality. 

 The following summary is taken from the bulletin : 



From tlio results of oiglit trials iu 1888 and five in 1889, tbirtccu in all, antl ni.ailc 

 iu eleven different localities, the following conclusions may be drawn : 



The most productive of the early varieties are Oxford, Puritan Early, .and Crown 

 .Jewel. Next in order stand Nott and Lee Favorite. Of the medium and late sorts 

 Empire State, Summit, Seneca Beauty, White Elephant, and Delaware rank the high- 

 est of those that are fully tested. Including early, medium, and late varieties, not 

 fully tested, those that are the most promising are Queen (New Queen), Eur.al New 

 Yorker, Superior (Burpee's Superior), and Minnesota Early. Early Ohio,Ohio Junior, 

 and Stray Beauty rank as the earliest, hut are unproductive. Albino and Clias. 

 Downing seem to be less leliable than formerly, i)robably owing to susceptibility to 

 blight. Northern Spy and Monroe Prize arc inferior in appearance, hence not val- 

 uable for market. The former is unproductive, and it is not i)robab]o that the latter 

 will rank very high in this respect. Oxford, Seneca Beauty, and Delaware show 

 comparatively little variation on different kinds of soil. , 



Field experiments with fertilizers (pp. 11-13). — During 1888 and 1889 

 acid phosphate (dissolved S. C. rock), Thomas slag, superphosi)liate 

 (dissolved bone-black), nitrate of soda, and sul})hate of ])otash singly 

 and the last three in combination, have been compared with farm ma- 

 nure and no manure as fertilizers for potatoes. In both yenrs the injury 

 to the crop caused by blight was so great that the results were unsat- 

 isfactory, except so far as they confirm the results of other tests. The
