RuTA Bagas. — Our turnips — Carter's Imperial Parple-Top 

 Swede — were grown on a light sandy loam soil, "broken up" 

 last spring. The ground was i)lou<>hed to a depth of ten 

 inches with a large Holbrook "Side Hill" plough, and after- 

 wards well pulverized with a heavy harrow. Drills, three 

 feet apart, were made with a light horse-plough, and five cords 

 to the acre of well-rotted barn-yard manure strewn in the 

 drills. This was covered with a plough, and the ridges levelled 

 and lumps removed with rakes. The seed was sown June 

 20th. 



The young plants were thinned to eight inches to a plant. 

 This is our usual method with this crop, and it seldom fails 

 us. 



As this year's crop has not been harvested, we give the 

 data of the crop of 1872, which was an average one, — cer- 

 tainly no larger than this year's will be, and the price a fair 

 average one. Last year's crop was not all housed, the major 

 part being taken from the field to the cars.
