general purposes. Fitted to give a speedy return of marketable 

 timber, but nothing more, under certain circumstances. 431-434 



Main question examined ; namely, the effects of the trenching and 

 manuring system on the quality of timber for ships of war. 

 Shown, from the well-known laws affecting growth in woody 

 plants, that instead of improving, it would sensibly deteriorate 

 all timber, and especially the Oak. Various illustrations of 

 this doctrine. Argument resolved into six practical conclusions, 

 founded on phytological principles, and supported by facts. — 

 Clearly demonstrated, that Sir Walter Scott has committed no 

 " Fundamental Errors," but that such errors have been com- 

 mitted by Mr Withers himself. — Low and unsettled state of the 

 Art of Planting on scientific principles. Billington, Loudon. 

 Messrs Pontey and Withers, being too much occupied with the 

 bulk of timber produce, altogether overlook its solidity and 

 durability. ----- 434-440 



Note V. Successful method of eradicating rushes. If proceeding 

 from underground water, to be effected by regular draining ; if 

 from tenacit3'' of soil or subsoil (the worst cause), by deep 

 trenching. — Details and cost of the process, under various cir- 

 cumstances. — Curious fact, that deep trencliing will render wet 

 land dry, and dry land moist, for any useful purpose, 440-444
