MONTHLY JOURNAL OF AGRICULTURE. 



A writer of great candor and credibility before the American Revolution, put 

 down the usual wheat crop above Albany at from 20 to 40 bushels. And here 

 would seem to be an appropriate place for introducing the following Tables 

 from one of Johnston's Lectures. They may serve for frequent reference, and 

 we are persuaded will be found very acceptable. Perfect and exact precision is 

 not expected in such cases, but who can be better relied on for a near and reli- 

 able approximation to it than he ? 



AVERAGE COMPOSITION AND PRODUCE OF NUTRITIVE MATTER PER ACRE, BY EACH OF THB 

 USUALLY CULTIVATED CROPS. 



1st. Average Composition. — The relative proportions of the several most important con- 

 Btituents contained in our cultivated crops vary, as we have seen, with a great number of 

 circumstances. The following Table exhibits the average composition of 100 paits ot the 

 more common grains, roots and grasses, as neai'ly as the present state of our knowledge 

 upon the subject enables us to represent it :

Some of the above numbers are approximations only. The proportions of fatty matter 

 especially, are in many instances very uncertain. 



2d. Gross Produce per Acre — The gross produce, per acre, of the different crop« varies 

 in different districts of the country. The weight of each crop in pounds, however, will, in 

 general, approach to one or other of the quantities represented by the numbers in the fol- 

 lowing Table :
