 their analogy in form and appearance, with the 

 productions of the northern temperate zone ! 



The inhabitants of the valleys of Aragua often

 ! month of February, many trees stripped of their 

 foliage, near the Hacienda de Cura, at Mocundo, 

 and at Guacara ; while to the South-East of 

 Valencia every thing presaged the approach of 

 the rains. I believe, that in the early part of

 plantations of tobacco in the whole province are
