■with llio exceptiou of crudo fiber, in wiiicli there is so.netimes an appreciable in- 

 crease. 



Whether the deereaso iii the diffe-stibility of the j^rasses after full bloom will offset 

 the increase of yield has not yet been determined. Presumably, the decrease in di- 

 gestibility is not so rapid with the grasses as with theclovers. 



OHCHAKI) GIUSS rs. TIMOTHY. 



While the yield of orchard j^rass was less than of timothy, the digestible organic 

 substance being about three-fourths that of timothy, its composition and digesti- 

 bility indicate a better quality of hay for milch cows and growing stock. Orchard 

 grass does not seem difficult to grow successfully in this State. It ripens with me- 

 dium red clover, which makes it desirable for mixing withtbat plant. Nev^ertheless, 

 its cultivation is adopted slowly, It has generally been held to be less readily taten 

 by stock than timothy, and the cost of the seed probably retards its adoption and 

 general culture for meadows. As a pasture grass it is conceded to be inferior to Ken- 

 tucky blue grass for this State.

ExrERi:\IENTS WITH VEGETABLES AND COMMERCIAL FERTILIZERS, 



James Troop, M. S. (pp. 1-11). — The experiments were couducted 

 with two objects in view : (1) Testing commercial fertilizers ; (2) testing 

 varieties. 



The bulletin contains a record of observations made during- the sea- 

 son of 1888, on varieties of potatoes, sweet corn, onions, peas, and sugar 

 beets, and also of plat experiments with fertilizers on jjotatoes, and is 

 illustrated with a diagram of the horticultural experiment held of 10 

 acres, showing the situation of different kinds of fruits planted. 



Commercial fertilizers on potatoes. — In this experiment each i^lat was 

 surrounded by others of the same size which received no fertilizers. 

 Several brands of commercial fertilizers were used. The Burbauk po- 

 tato was planted on all the plats A.\}v\\ 2G. The " Eural trench system" 

 was used tliroughout. There were differences in the depth of trenches, 

 in the phuiting of potatoes, and in the ways of applying the fertilizers.. 

 The drought of the season was very severe and materially interfered 

 with the success of the experiment. Results are stated in detail in 

 tabular form. 



Varieties of potatoes. — The yield of seventy-seven varieties of potatoes 

 is given in bushels per acre. 



Varieties of sweet corn, onions, and peas. — Here are given tabulated 

 notes on the development, yield, and quality of each of forty-five va- 

 rieties of sweet corn ; colors, sizes, and yields of twenty-eight varieties 

 of onions; and dates of marketable maturity of thirty-two varieties of 

 peas.
