 live varieties of su.ii'ar beets yrown on the station <;rounds nave per- 

 centages of sugar in the Juice ranging from 12.75 to 14.30. 



Effects of phosphoric acid from different sources on imtatoes (pp. 187- 

 »101). — The object of this experiment was to test the relative eftects of 

 like money values of phos])hatic slag, ^lona Island giiano, apatite, 

 South Carolina phos])hate (tloats), and dissolved boneblack for pota- 

 toes. The land used (a fair sandy loam) had been prepared for the 

 exiuniment by cropping for the 3 jirevious years with corn, Hungarian 

 grass, and leguminous crops, respectively, \Aithout api)lying fertilizers. 

 It contained five plats, approximately one seventh of an acre each, 

 separated from each other by strips 8 feet wide. All the plats received 

 the same amount of ])otash-magnesia sulphate and nitrate of soda. 

 The source of i)lios])horic aci<l was ditierent on each plat, an amount 

 being applied in each case which at the local market prices cost §6.2.j per 

 acre. Thus i)hos]>hatic slag, ^Nfona Island guano, and South Carolina 

 lock were each applied at the rate of 8.")0 jxninds per acre, dissolved bone- 

 black at the rate of 500 pounds, and apatite at the rate of 2,000 ]>ounds. 

 P>eauty of TTebron potatoes were planted on all the jdats, in rows .3;^ 

 feet ai)art, with the hills 18 inches apart in the rows. 



Maturity seemed to have been hastened by a drouth occurring in .7nl\ . 

 The potatoes were harvested August 12-14, and assorted into market- 

 able (sold at 00 cents i)er bushel) and small (sold at 20 cents). The 

 yield and financial statement for each j^lat and analyses of the phos- 

 l)hates used are tabulated. A statement of the yield and value per 

 acre follows:
