Wheat weighs sixty pounds to the bushel, and turnips 

 about forty. Thus, it would seem, that as much nourish- 

 ment is to be derived from one bushel of wheat, as from 

 about twenty-seven of turnips. This, however^is not the 

 case. 



What is called the stimulous produced by distentron must 

 be taken into the account, in forming a proper estimate of 

 the effects produced, in supporting life, by any kind of food; 

 and it is on this account that, perhaps, fourteen bushels of 

 turnips, particularly when boiled, would sustain life as long, 

 or faten as much, as one bushel of wheat.

OAK (Quercus.J Mr. Green^ in his < Catalogue of plants 

 indigenous to the State of Newyork,' enumerates fifteen 

 different kinds of oak, to wit; the common white, the swamp, 

 the yellow-chesnut, the scarlet, the Spanish downy-red, ther 

 long-stalked, the scrub or barren, the large-fruited, the 

 rock-chesnut, the rock, the mossy-cup, the various-leaved, 

 the black-jack, the post-white, and the pinoak. 



With some of the above kinds we are not acquainted. 

 The black-jack abounds in the middle States. 



There is also the liveoak of the Southern States, which is 

 uncommonly hard, when dried, very durable, and esteemed 

 the best for shipbuilding. 



The swampoak is very firm, tough, and durable; and, 

 when cultivated, it should be in such grounds as those in 

 which it naturally grows. 



The whiteoak, which grows in moist uplands, is of rapid 

 growth, firm in texture as any of the northern oaks, and is 

 mostly cultivated. 



The liveoak should be cultivated where it naturally 

 grows. 



See FOREST, for an approved method of cultivating the 

 oak. 



It may also be planted in nurseries, and then transplant- 

 ed, at pleasure. 



Mr. Forsyth, in speaking of those which are raised in 

 nurseries, says, it is a generally-received opinion, that when 

 an oak looses its tap-root, in transplanting, it never produces 

 another; but this he found to be a mistake. He transplant- 

 ed a bed of oak-plants into a fresh bed, cuting off the tap- 

 roots near the small fibres shooting from them. The second
