Conclusions. — In two trials in two seasons we have received no return in milk and 

 butter from feeding a grain ration to cows on good pasture. 



In one trial witli cows soiled on fresh grass we have received in increased milk and 

 butter production and in saving of grass consumed barely enough to pay for the cost 

 of the grain ration added. 



In neither case has any allowance been made for increased value of manure when 

 grain is fed, which would bo considerable in amount, but exceedingly difficult to 

 estimate with exactness. 



We are still of the opinion that several repetitious of this experiment will be needed 

 before the matter can be considered conclusively settled.

The WORK of the horticultijjral division, W. P. Massey, G. E. 

 '(pp. 3-10). — But little systematic work in horticulture had beeu under- 

 taken by the station up to December, 1889, when the author was ap- 

 pointed horticulturist. During 1890 a number of varieties of large and 

 small fruits have been planted, and comparative tests of such vegeta- 

 bles as are commonly grown in the South for shipment to IsTorthern 

 markets have been begun. These incUide peas, cabbages, tomatoes, 

 Irish and sweet-potatoes, and sweet-corn. With a view to producing 

 an early variety of sweet-corn suited to ]!!^orth Carolina, seed of a num- 

 ber of early Northern varieties has been procured, from which by cross- 

 ing and selection it is hoped to obtain a desirable variety. Twenty-two 

 varieties of Irish potatoes, 11 of sweet-potatoes, 40 of tomatoes, and 10 

 of peas were grown in 1890, Early and late cabbages will also be tested, 

 and an attempt made to grow Pyrethrum roseuni and einerarifollum, 

 from which powder may be made for insecticidal uses. The additions 

 to the small and large fruits previously grown at the station include 

 40 varieties of apples, 40 of peaches, a number of grapes, 36 varieties 

 of figs, a California plum {Prnniis subcordata). and 2 varieties of Jap- 

 anese orange {Citrus trifoUata and Satsuma). It is proj)osed to illus- 

 trate at the station various methods of pruning and training grapes, to 

 study insects and fungous diseases of plants with a view to devising 

 remedies, and to do something in ornamental horticulture and arboricul- 

 ture. An arboretum will be begun on the college grounds and a new 

 greenhouse will be constructed. The list of plants now growing at the 

 station, as given in the bulletin, includes 57 varieties of apples, 9 of 

 pears, 51 of peaches, 21 of plums, 6 of cherries, 3 of quinces, 6 of nuts, 

 123 of grapes, 36of figs, 8 of raspberries, 7 of blackberries, 17 of straw- 

 berries, 2 of currants, 2 of gooseberries, and 13 of osier willows. 



Value of pea- vine manuring for wheat, J. E. Chamberlain, 

 B. S. (pp. 11-13). — To test the value of pea vines as a green manure in 

 preparing land for wheat, land from which a crop of cabbages had been 

 taken off was divided into equal parts, and black cow-peas sown on 

 one half, while the other half remained vacant. Owing to late sowing 

 the pea vines had not reached maturity at the time they were plowed 

 in (middle of October). Seven plats were laid out so that one half of
