White Hall Creek. 

 (Chart of Natural Oyster Bars, No. 2.) 



White Hall Creek, situated adjacent to Annapolis Koads be- 

 tween Hackett and Greenbury Points, is in reality a small bay, 

 having an area of about one square 1 mile, into which three 

 creeks enter from the north. It contains two small bars having 

 an area of forty-six and six acres, respectively, and a Small part 

 (110 acres) of a large bar, the greater part of which is located 

 in the adjoining section. The off-shore boundaries of these 

 bars are covered by water eight to fifteen feet in depth, but the 

 in-shore boundaries of each follows the six-foot curve. The 

 greater part of the oyster-producing bottoms is composed of 

 hard sand, but as the central part of the section is- approached 

 the sand becomes mixed with an increasing proportion of mud 

 until the bottom becomes loose and soft. The density of the 

 water over the northern part of White Hall bar was 1.0036 on 

 August 6, 1906, but on December 11 it had increased to 1.0108. 

 No observations on the velocity of the currents were made in 

 this section. 



The barren bottom which can probably be made productive is 

 situated between the natural bars and above Sand Spit bar and 

 aggregates about fifty acres. This includes about ten acres of 

 the oyster ground just north of White Hall bar which was 

 found to be too depleted to be included as a part of this bar. 



Severn River. 

 (Chart of Natural Oyster Bars, No. 2.) 



The oyster-producing part of Severn River terminates at a 

 point at the head of Round Bay about eight miles above the 

 mouth of the river as established by a line connecting Green- 

 bury and Tolly Points. The river at its mouth, as above de- 

 fined, includes a part of Annapolis Roads and is about two 

 miles wide, but from Annapolis to Round Bay its average width 

 is about one-half mile. A chain of natural oyster bars, twenty- 

 four in number, aggregating an area of 989 acres, occupies prac- 

 ticallv all of the bottom on both sides of the river between the
