figures  6-45  and  6-46,  or  the  “closed”  or  “boxed cornice” shown in figure 6-47. A short extension of a cornice along the gable-end wall of a gable- roof structure is called cornice return (fig. 6-48). Finish  along  the  rakes  of  a  gable  roof  is  called the gable cornice trim (fig. 6-49). The rafter-end edges of a roof are called EAVES. A hip roof has eaves all the way around. A gable roof has only two  eaves;  the  gable-end  or  end-wall  edges  of  a gable  roof  are  called  RAKES. Wall Sheathing The  outside  wall  sheathing  or  covering  on  a frame structure consists of either wood siding or paneling,   wood   shingles,   plywood,   fiberboard, hardboard,   and/or   other   types   of   materials. Masonry,  veneers,  metal  or  plastic  siding,  and other non-wood materials are additional choices. There  are  two  general  types  of  wooden  board siding:  drop  siding  and  common  siding.  DROP SIDING (fig. 6-50) is joined edge to edge (rather than  overlapping).  COMMON  SIDING  consists of  boards  that  overlap  each  other  single-wise. Figure 6-48.-Cornice return. Boards  not  more  than  4  ft  long  are  called clapboard; boards in longer lengths but not more than 8 in. wide are called bevel siding. A number of  drop  board  and  common  sidings  can  be  used horizontally  or  vertically  (fig.  6-51),  and  some Figure  6-50.-Types of drop siding.
