Adobe  brick  are  made  at  many  points  from  the  calcareous  valley
clays,  and  common  burned  brick  are  also  manufactured  at  different
points.  The  Cretaceous  shales  at  Las  Vegas  have  yielded  good  results
with  the  dry-press  brick  process.  Fire-clays  have  been  worked  at
Socorro  and  were  formerly  made  into  fire-brick.
