 extent, between our grasses and the grasses grown in 

 a comparatively moist climate, where they have the 

 advantage of more frequent rains, which push them to 

 a more complete development and give them greater 

 luxuriance, increasing, of course, the quantity of their 

 produce, while their quality cannot be improved in the 

 points alluded to.
