1863' On the Culture of Turnips* I J "5 



ly brought back to a Iev51. The cxpcnce of fpreading the dun;^ 

 into the drills is very little more than when it is i'pread on th« 

 furface at large ; and this trifling dillercnce (not fixpcnce per acre) 

 is ten times more than compenlated by the extra benefit gained 

 by the crop, in conlequence of the dung being completely cover- 

 ed in. It is not cuftom.ary to earth up turnips, unlets when they 

 are grown on wet linds, as fuch a pracVicc prevents the root from 

 fweliing in iize \ confequently the danger to flicep, when fed 

 upon turnip fields, apprehended by our correfpcndcnt, can ver/ 

 rarely take place. 



Though our opinion, on this fubjedV, coincides with what was 

 given by the Northumberland farmer, yet we muft acknowledge 

 that the arguments ufed on the other fide, by our Yorkfliirc 

 friend, are ingenioufly and ably itated. They difplay confider- 

 able knowledge in the practice of agriculture, and prove the 

 writer poiTeiled of an ardent, though miilaken dcfire to promote? 

 the welfare and'profperity of that fcience. N.

Account of the Feat Mojfes and Shell Marl on the Eflate of DunnU

 ALanufcript Hijlory of Feat MofSy by Andrew Steele Efq, 



The changes that have occurred, and the revolutions that have 

 taken place during ages, and are ftill in their progrefs, in the 

 falling up of the vallies of the earth, cannot perhaps be more 

 beautifully difplayed to the philofophic eye, than by examining 

 Relleneth peat-mof-^, the property of GeoiFgc Dempller Efq., in 

 the parifh of Forfar. 



Situated 200 feet above the level of the fea, in a hollow from 

 which the water of a copious fpring hath had no clear and fuffi- 

 cient ifTue, this peat-bog, confilling of about 70 acres, muft have 

 been once a lake. Indeed, that is fufBciently obvious, not only 

 from its connexion v/ith a very confiderable lake, called Refheneth 

 Loch, alnloft a mile in length, but efpecially from a bed of (hell 

 marl found beneath the peat, and fituated immediately above the 

 folid ground. The bed of marl (of which fub (lance there is alfo 

 a great quantity found in Reflieneth Loch) is in fome places i^ 

 feet in thicknefs, gently diminilliing towards the margin of the 

 mofs. Its average thicknefs is about 5 feet •, but the layer is very 

 irregular. On difTolving a portion of this marl in the muriatic 

 acid, I found it a very pure calcareous matter, containing only 

 about a tenth part of its weight of peatv and other fubftanceS.
