The estimate of material to be excavated, for this ditch was cal- 

 culated in 2,000-foot sections, from the profile data. Three highway 

 bridges will be required at the points where the proposed ditch crosses 

 the public roads, one of 35 feet span and two of 30 feet. 



Wolf Bay lies in the flat woods section of the district. Only a 

 small part of the basin drained is under cultivation, the greater part 

 being fiats and bays covered with timber and brush. It has two 

 forks, along both of which the swamp varies greatly in width but 

 averages about 300 feet. The fall on this branch, from the hea<l of 

 the east fork, is about 35 feet in 4.6 miles. The proposed improve- 

 ments on the east fork of this branch consist of a minimum dredge 

 ditch for its entire length of 24,250 feet, except that the upper mile 

 should be a handmade ditch, while the west fork should have a 

 smaller ditch and is considered as lateral ditch No. 10. Four new 

 bridges will be required, one span of 15 feet and three of 30 feet. 



Causeys Branch has two outlets, part of the water going direct to 

 Black Swamp through Shumans Bay and part flowing south through 

 Titi Branch. Most of the drainage area is rolling land under culti- 

 vation. The swamp along Causeys Branch is quite narrow at the 

 upper end, about 600 feet wide from the railway to Shumans Bay, 

 where it widens to about 1,000 feet, then it rapidly narrows before 

 reaching Black Swamp. The fall on the branch is comparatively 

 large, 44 feet in 3.3 miles, or 13.3 feet to the mile. It is proposed to 

 carry all the water by the more direct route through Shumans Bay, 

 the improvement to consist of a handmade ditch throughout the 

 entire length of 18,425 feet. Two new 15-foot bridges will be needed. 



Titi Branch drains an area largely under cultivation, with rather 

 rolling topography and a good fall from the adjoining lands to the 

 branch. The swamp along this branch varies much in width, the 

 upper end and middle section being wide, while the lower end is 

 narrow. The fall on Titi Branch is quite large, amounting to 43 feet 

 in 3 miles. The improvement proposed for this branch consists of a 

 handmade ditch 16,275 feet long. One 15-foot bridge will be re- 

 quired. 



Long Branch is the drainage outlet for a basin quite flat and 

 covered with timber at the upper end, but a little more rolling and 

 largely under cultivation at the lower end. The swamp along this 

 branch averages about 200 feet in width, and it has a fall of about 

 28 feet in 3.2 miles. The proposed improvement consists of a hand- 

 made ditch through the entire branch, a distance of 17,900 feet. 

 Three 15-foot bridges will be required. 



Lyas Bay drains good, rolling land, a large part of which is now 

 under cultivation. The swamp averages about 700 feet wide. The 

 proposed, improvement is a handmade ditch 9,900 feet long, running 

 from the Southern Railway southwest to the bay, thence through it
