Whether Oak Plants or Aeorns ought to be used in forming Oak Plantations is a 

 question, respecting the answer to which planters are not fully agreed ; though, 

 upon the whole, we believe, plants are preferred. A doubt, it is probable, would 

 never have been raised OB the subject, had it not been found that, under ordinary 

 circumstances, the oak suffers more by transplanting than the elm, the ash, the 

 beech, and other similar trees ; which is partly owing to its natural delicacy, and 

 partly to its depending, when young, chiefly on its taproot, and from its not 

 producing, for some years, many lateral roots, unless forced to do so by art. 

 When, however, the oak has been two or three times transplanted in the nur- 

 sen before its final removal, it will produce a sufficient number of lateral roots 

 to insure its growth, if carefully removed; and, for this reason, we should, in 

 almost every case, prefer using strong transplanted plants to acorns. We 

 have already remarked that oaks, after they have attained a ceftain size, are 

 more successfully transplanted than seedlings of one or two years; a fact 

 which will be found to hold good with all trees whatever which have taproots 

 of extraordinary dimensions when young. One reason which some give for 

 preferring acorns is, the alleged injury which oak plants sustain by the loss 

 of the taproot, which, it is said, they never regain. This opinion, however, is 

 well known to be erroneous ; it being as natural, in the case of seedling 

 oaks, for that part of the plant which is under ground to reproduce a leading 

 or tap root when that has been cut off, as it is for the part above ground to 

 reproduce a leading shoot after that has been removed. It is also equally well 

 known, that the taproot is only found, in oak and other trees, when in a young 

 state ; and that no oak or other tree, when cut down, was ever found to have 

 anything like a perpendicularly descending main root in any way comparable 

 to the perpendicularly ascending trunk of the tree above ground. The con- 

 sequence of sowing an acorn where it is to remain, and not cutting through 

 the taproot, is, that it remains a longer period before putting out any lateral 

 loots ; but whether these lateral roots are put out sooner or later, can have 

 \cry little influence on the growth of the tree under ordinary circumstances, 

 and certainly none on the value of the timber which it produces. It is easy to 

 conceive that, if the surface soil on which an acorn is planted is much richer 

 than the subsoil, something in rapidity of growth will be gained by cutting off 

 the taproot, so as to force the plant to send out lateral roots sooner than it 

 otherwise would do ; but, though something is gained by this, something, also, 

 will be lost; because the supply of water, so essential to all plants which 

 have naturally taproots, in a very young state, will be considerably diminished. 

 In warm climates, therefore, and in all cases where a saving of first cost is an 

 object, we should prefer acorns to plants; but in tolerably moist climates, and 

 in deep alluvial or marl} soils, or where the surface soil is rich, and where the 

 object is to produce oak trees as soon as possible, we should recommend strong 

 plants. 



The following judicious observations on the subject of the taproot were 



communicated to the Bath and West of England Society by a planter and 



manager of timber of very great experience, Thomas Davis, Esq., of I'ortway, 



near Warminster. The taproots Of young oak trees, Mr. Davis says, support 



the tro during a given period, which may vary in the number of years from 



various circumstances, soil, situation, (Sec, but is limited in effect by the ne- 



. . of the plant; and so soon as as the lateral roots take firm hold of 



the land, and are enabled to undertake the duty of support, from that time the 



taproot ceasei to be useful, and at no distant subsequent period ceases to in-

therefore concludes, — " 1st, That an oak seedling, or sapling, from '.i to 5
