Mr. Ignaz Matausch, expert preparator, and the group at an early stage in the work. The 

 miniature sketch nicdel at the upper left hand was constructed at the seashore (Woods Hole) for 

 study of composition. It is made to the scale of three inches to the foot. A framework for the 

 finished group, six feet in length, was constructed in the Museum, and the sea-bottom modeled in. 

 Temporary wax dummies were used to determine the final position of the various worm-tubes

A cavity is represented arbitrarily hollowed out among the roots of the eel grass to disclose 

 the worms burrowing in the mud. A clam-worm (center) is attacking the iridescent opal worm. 

 Beak-throwers are swimming corkscrew fasliion [at left in cut], or throwing out a club-shaped 

 proboscis armed with hooks (at right in cut]. A coiling fringed worm [middle below) extends its 

 threadlike breathing organs in all directions. (Accurate representation in wax and glass. See 

 preliminary sketch model in lower left hand corner of cut above]
