sliuctois of transplanting machines, tliat their vakie in a 

 great measure hes, in the weight of wood and iron they con- 

 tain. My conception of it, on the other hand, is precisely the 

 reverse ; as I believe, that the smaller the quantity of those 

 materials, the greater the utility of the implement. If it be 

 true, that the greatest success, and the greatest despatch 

 united, form the character of the most perfect transplanting- 

 work, it follows, that heavy implements of this sort, unless for 

 work of uncommon magnitude, are doubly inexpedient; 

 first, on account of the expense which they cost in the 

 beginning ; and secondly, on account of the still greater 

 expense, which it erelong costs to use them ; for time need- 

 lessly lost is money improvidently thrown away. Better that 

 a machine should break down twice in your life, from being 

 somewhat too light for its work, than that it should cost you 

 three times its price in labour, in dragging a superfluous load 

 of wood and iron about your park ; for thus there would be a 

 loss of both time and money. This, however, is a style of 

 estimate, which only practical persons will understand, and 

 only economists of time will duly appreciate. If a man 

 remove only three trees in a twelvemonth, it signifies little 

 w^hat sort of machine he happens to use. But if he remove 

 sixty or a hundred trees, twenty or thirty times the cost makes 

 a great figure in the calculation. Now, supposing that he 

 executed but a third part of the work last mentioned, I am 

 satisfied that there would be economy in having two ma- 

 chines, calculated to the scale of his work ; the machine for 

 the lesser trees being light, and possessing small power, the 

 other for the greater trees being weighty, and possessing 

 much greater power. In this way, power (which, as the best 

 philosophers have agreed, is nearly the synonyme of money) 

 would never be idly employed, but judiciously suited to, 

 though never suffered to transcend the immediate object of 

 the planter. 



As this reasoning appears to be conclusive, I shall now
