Fabricated of l6-gauge (0«06 inch) monel metal, the cylinder is 

 four feet in length, with an inner diameter of Ii-$/8 inches. This 

 diameter exactly accomodates the Atlas current meter, which, after 

 insertion into the cylinder, is secured by three lugs (set in fairings) 

 and wing-nutso Soldered 1/8" back from the rim of the fore-end of 

 the qrlinder is an inner band of monel, 3/U" ty 3/U'S to support the 

 plankton net collar and to provide a seat for its flanpe, to furnish 

 a medium for seating the machine screws used in securing the nose- 

 piece, and to impart added strength to this portion of the cylinder. 

 Three slots cut in this band permit passage of the screen support 

 rods (see figs© 2 and 3), Stabilization when towing is affected by 

 means of a vertical fin and two stabilizers (of l6-gauge monel), 

 aided by the depressor. Two towing plates, ten inches in length, 

 one inch in height and a half inch in thickness, are drilled with 

 seven half-inch holes (see cut-away, side view, fig. 2) to achieve 

 optimum towing performance ty providing a selection in points of 

 attachment for the towing and depressor cables.
