year the Cabbage and Cauliflower in our "trial grounds" 

 were attacked by the Cabbage Maggot at the roots early 

 in May. A small handful of Peruvian guano was at once 

 strewn around each plant and hoed in around the roots. 

 This at once started an unusual vigor of growth, which 

 sustained the plants until they matured excellent heads. 

 Understand, the guano probably did not injure the in- 

 sect; it only enabled the Cabbage to outgrow its attack. 



CLUB ROOT. 



For the destruction of the insect which causes 

 the excrescence known as "club root" in Cabbage, 

 a heavy dressing of lime in fall and spring will 

 check it to a great extent. In fact, on lands 

 adjacent to the shores of New York Bay, where the 

 soil is mixed v/ith oyster shell, " club root " is rarely 

 seen. Cabbage having been grown on some fields suc- 

 cessively for fifty years without a trace of it being seen, 

 showing that the insect that causes the "club root " can- 

 not exist in contact with lime; for it is found that on 

 lands where there is no oyster shell deposit, a quarter of 

 a mile distant, Cabbages cannot be grown two years in 

 succession on the same land, unless heavily dressed with 

 lime, and even then it is always deemed safest never to 

 plant Cabbages two years in succession on the same 

 ground; for while such crops as Onions show but little 

 benefit by rotation with other crops, Cabbages, perhaps 

 more than anything else, are benefited by such alterna- 

 tion. When it can be done, nothing is better than to let 

 the Cabbage crop be alternated with grasses, such as 

 German Millet, Timothy, or Clover, or a crop of Oats or 

 Rye. This is the method pursued by many of the Long 

 Island market gardeners, who grow for the New York
