118 APPENDIX. 



ashes carried to the compost heap, as they are not 

 needed on this soil. 



These plats were set with sods, with most excellent 

 success one-half rod gave me this season one bushel 

 of berries, which is at the rate of at least three hun- 

 dred and twenty busliels to the acre. These experi- 

 ments show clearly that the plant cannot be set in this 

 grass with any prospect of success. There is another 

 kind of grass called polly pod, also, small brake, Dry- 

 opteris ihelypleris, which, as far as I have seen where it 

 covers the ground, casts so much shade that the 

 vine cannot succeed in it. It is more easily pulled up 

 than the buckthorn 5 and when dried and burned, 

 vines may be set with good results. 



There is another kind called by some the broad- 

 leaved sword-grass, and by others broad-grass, and by 

 botanists wool-grass, scirpus eriophorum. It grows in 

 round plats or clumps, varying in diameter from three 

 to twelve feet. In the piece I presented to you for 

 examination there are several plats of this grass, 

 which show that the vine cannot take root in it. 



Upon this same piece of ground is another kind of 

 grass covering some two rods called carex lacustris, a 

 coarse kind of sedge-grass; its general appearance 

 does not differ from wool-grass, the blades of which 

 are no? so thickly set in the soil as the wool-grass, yet 

 sufficiently so as that the vine succeeds with dif- 

 ficulty.
