over Squeteague Harbor which opens from the former by a 

 winding narrow passage. Except for the dredged passage, most 

 of the region can be waded at low tide. Much of the ground in 

 Cataumet and almost all in Squeteague Harbor is left bare by 

 the spring tides. The collecting is over a wide range of bottom: 

 sand, mud, scattered rocks and gravel with and without eel grass 

 and other sea-weeds. There is a somewhat sparse collection of 

 rocks along the shore line. 



Lackey's Bay. — Lackey's Bay belongs to the Hadley Harbor 

 complex. It is located on the Vineyard Sound side between 

 Naushon and Nonamasset. The part studied forms an ex- 

 panded entrance to Middle Gutter which, by the construction of 

 a causeway, has become Blind Gutter. The current is much 

 diminished by the causeway and the inner part of the bay is 

 deeply overlaid with muck. Eel grass is abundant. The region 

 most studied is about 400 yards long by 200 yards wide and is 

 separated from the Sound by a sand bar which is left bare at 

 low tide. 



Dredging. 



The dredging has been largely in three localities in Vineyard 

 Sound. These are the sand dollar bed (Map, No. 8) near the 

 east side of the entrance to Tarpaulin Cove in about 20-30 feet 

 of water. The bottom material brought up by the coarse dredge 

 used is largely composed of shells. The starfish hole (Map, No. 7) 

 is further east and still off Naushon, has about 90 feet of water. 

 The Chcetopleura grounds (Map, No. 3) off Nobska have about 

 sixty feet of water. The bottom is decidedly pebbly. Some 

 dredging has been done further east on or near the planted 

 oyster bed (Map, No. 2) in Falmouth Harbor. The bottom 

 here is sand and gravel in about 60 feet of water. In 1921 we 

 dredged off the west entrance from Vineyard Sound to Great 

 Harbor (Map, No. 4) in about 80 feet of water. This is over an 

 Amarxcium pellucidum bed. 



In 1920 we dredged in Great Harbor (Map, No. 5) : at the 

 east end of Nonamasset in 10-12 feet of water; in the Fish 

 Commission Hole at a depth of 50 feet and at the West end of 

 the passage in Woods Hole in about 20 feet of water. 



The dredging work has been largely incidental and the results 

 are given chiefly as a means of comparing the more extensive
