the mere presence of the cabbage causes stump foot on 

 succeeding crops grown on the same soil. This is 

 proved by the fact that where a piece of land in grass, 

 close adjoining a piece of growing cabbage, had been 

 used for stripping them for marked, when this was broken 

 -up the next season and planted to cabbage, stump foct 

 appeared only on that portion where the waste leaves 

 fell the year previous. I have another instance to the 

 same point, told me by an observing farmer, that on a 

 piece of sod land on which he run his cultivator the year 

 previous when turning his horse every time he had cul- 

 tivated a row, he had stump footed cabbage the next 

 season just as far as that cultivator went, dragging, of 

 course, a few leaves and a little earth from the cabbage 

 piece with it. Still, though the mere presence cf cab- 

 bage causes stump foot, it is a fact that under certain 

 conditions cabbage can be grown on the same piece of 

 land year after year successfully, with but very little 

 trouble from stump foot. In this town (Marblchcad) 

 though, as I have stated, we cannot on our farms follow 

 cabbage with cabbage, even with the highest of manur- 

 ing and cultivation, yet in the gardens of the town, on 

 the same kind of soil, (and our soil is green stone and 

 syenite, not naturally containing lime,) there arc in- 

 stances where cabbage have been successfully followed 

 by cabbage on the same spot for a quarter of a century 

 and more. In the garden of an aged citizen of this 

 town, cabbages have been raised on the same spotofland 

 for over half a century. 



The cause of stump foot cannot therefore be found in 

 the poverty of the soil, cither from want of manure or 

 its having been rendered effete from over-cropping. It 

 is evident that by long cultivation soils gradually have 

 diffused through them something that proves inimical
