ports, containing a full description of the character and the results of 

 our iuvestigations, however detailed the latter may be, cannot equal 

 the impressions produced by a personal visit to the field of actual 

 operations, at important periods of observations, a cordial invitation 

 is hereby extended to all parties interested to visit the grounds of the 

 station during the present season. 



The cultivation of a variety of farm crops, and in particular of re- 

 puted fodder crops, presents at this period of the year, a special fea- 

 ture of interest to visitors. 



An intelligent, critical discussion of our plans and methods upon 

 the field of actual observation cannot otherwise but benefit managers 

 and visitors, and tend ultimately to promoie the best interest of our 

 farming community. All who favor us with their visit will find by 

 calling at the director's oflSce in the labaratory building of the station 

 a well informed guide to conduct them over the fields and the 

 barn. 



The observations with reference to the effect of special articles of 

 plant food on the growth and general character of Indian corn are 

 continued. Inquiries regarding the influence of different forms of ni- 

 trogen, as well as of tlie absence of nitrogen on the quantity and qual- 

 ity of the corn crop, have taken the place of those with potash com- 

 pounds of previous years. .Several reputed varieties of ensilage corn 

 are raised to compare their relative merits under our local conditions. 



The study of the growth and of the character of prominent grasses, 

 and of different leguminous plants when raised upon Inauured and un- 

 raanured lauds, is carried on as in preceding years. Bokahara clover, 

 (Melilotus alba,) and Sainfoin, (Onobrychis sativa) have been sub- 

 stituted for Lucern, (Medicago sativa.) and Red Mammoth clover, 

 Kentucky Blue grass, (Poa pratensis,) has taken the place of English 

 and Italian Rye grass, (Lolium perenue and Italicum.) 



Southern Cow pea, Serradella (Ornithopus sativus,) and a mixed 

 crop of vetch and oats are cultivated upon an nrea sufficiently large 

 to supply green fodder for from five to six milch cows during the 

 months of July, August and a part of September. 



The experiments with j)otatoes described in previous reports arc 

 repeated with some modifications. Of interest in this connection is 

 a series of experiments under the especial direction of Prof. Hum- 

 phrey, to study the cause of scab on i)ot;)toes. Attention is invited 

 to his inquiries on pages 3 and 4 ot this bulletin.
