shrinkage in the three forms of presses were as follows : 

 Seven percent for the slat and cord press, nearly eight 

 percent for the 40-pound board press, and fourteen per- 

 cent for the2V^-pound board press. Strong preference is 

 given for the slat and cord press, because of its efficiency 

 and convenience. Each half of the press is 12x18 inches, 

 made of seven slats, % inches wide and Vs inch thick ; 

 and four cleats 14 inches long (projecting one inch on 

 each side) and about i/^ inch wide and thick. Ven- 

 tilators are used when many specimens are put in the 

 press at one time, made of similar cleats but only 12 

 inches long ; fourteen slats being used, seven nailed on 

 each side. The pressure is secured by passing a cord 

 over the projecting and groved ends of the cleats on 

 the two sides.
