Dear Sir, 



I send you a copy of our notes from the summit of the Sierra de Sandia in the 

 Albuquerque Mountains, of which I talked to you when I had the pleasure of seeing you in 

 St. Louis. 



« The trees stop before arriving at the summit of the sierra; the last ones are similar in 

 growth as on the alps, they are pines. AH the crests of the sierra are naked and deprived 

 of trees. On the very summit we found Mamillaria and in the ravines Opuntia. I also 

 found on the summit three spécimen of Hélix ( sneakly ) or escargot. Finally we 

 descended in a ravine that reminded me of of the "Dole in the Jura", where the trees are 

 not very tall on the path where we energetically climbed. Here they stopped at 250 feet 

 before reaching the summit." 



I can guarantee the exactness of thèse notes written the very evening of our excursion. I 

 hope they can be useful to you. 



Your devout servant, 



Jules Maroon
