11^ gallons, as the gallon weighs 7^ lbs. ; but they reckon that 

 good trees give 6 livres (12 lbs.) one with another." In the 

 article Olive, in Michaux' North American Sylva., vol. 2, page 

 196, Mr. Hillhouse observes, * the mean produce of a tree may 

 be assumed in France, at 10 lbs. (1^ gals.) ; and in Italy at 

 15 lbs. (2 gallons,) ; but single trees have been known in the 

 productive season to yield 300 lbs. (41 gallons). Young 

 states the produce of a field of 209 trees in Tuscany to 

 have been in 



1786, 30 barrels, (150 lbs. each) or 615 gals.

66 barrels, 1352, " or 



average per annum of 338 gallons, being 1| gallons per tree.' 

 On a very bad stony soil, though in the plain, I found it took 

 20 trees of 25 years' growth to yield a barrel of oil (20^ gal- 

 lons) ; but in a fine soil and with very old trees, a barrel per 

 tree has been known.' 



" From these statements, assuming that the district to which 

 I have conjecturally limited the olive culture has a climate as 

 favourable for it as that in the South of France, we may place 

 the product of a tree in full bearing, as giving a mean annual 

 yield of one gallon of oil, or 25 gallons to the acre, when the 

 land is cultivated at the same time in some other crop, or at 

 50 gallons if exclusively devoted to the olive. Estimating the 

 oil at the moderate price of 75 cents per gallon, and the value 

 will be in the former case, $18f per acre, and in the latter, 

 $37^. But to the first must be added the value of the corn or 

 other crops cultivated on the same land ; and which may be 

 put down at nearly a full crop every second year, as the trees 

 are reckoned in Italy to diminish the grain crop only one- 

 fifth. 



" If the facts given above are sufficient to prove the impor- 

 tance and practicability of cultivating the olive among us, no 

 impediment is presented by the difficulty of propagating it, as 

 it is readily increased by seed, by cuttings, suckers, portions 

 of the root, or by grafting. The mode of raising by the seed
