as Oyn's Brook. It rises north of the railway, in the parish 

 of Feering, and is known as Domsey Brook until it enters 

 East Thorpe. Thence it flows through Massing and Inworth 

 to its confluence. Another small rivulet enters the Black - 

 water near here, on the same (left) hank. Eising on Tiptree 

 Heath, in the parish of Messing, it flows north-west through 

 Grreat Braxted and Inworth to the hridge below Gray's Mill, 

 Kelvedon. At Rivenhall End another stream enters the 

 Blackwater on the other side from Cressing. It is known as 

 Cressing Brook, and lower down as Rivenhall Brook. Near 

 Witham the Blackwater receives on its right bank a large 

 tributary from Bardfield and Braintree. This is known as 

 the Podsbrook, or below Braintree as the Brain, and, flowing 

 past Black and White Notley, is inaccurately marl^ed as the 

 Blackwater in Mr. Gibson's map. The Blackwater enters 

 the Chelmer navigation at Maldon. The Chelmer rises south 

 of Debden, flows past Thaxted to Tittey, where it receives on 

 the right bank a stream from between Chickney and the main 

 source, to Dunmow, below which it receives a tributary from 

 Lindsell and Stebbing, and so on to Chelmsford, where it 

 receives the Cann. The Cann rises near Great Canfield and 

 High Roothing, and flows- past Good Easter and Chignal 

 St. James to the Warren Farm, where it receives on its right 

 bank a tributary (the name of which is unknown, but which 

 might well be termed Roxwell Brook) that rises near Clerks, 

 between Blackmore and Shellow, and flows through Roxwell. 

 Nearer Chelmsford the Cfinn receives on its left bank a tiny 

 stream from Brick Chignal, and on its right the important 

 stream, the Wid. The Wid rises near Thorndon Hall, 

 Brentwood, flows to Mountnessing, where it receives another 

 stream partly from Navestock, and partly from Blackmore 

 and Doddinghurst (name ?), on to Margaretting, Widford, 

 and its confluence w^ith'the Cann. The length of the Wid is 

 stated at thirteen and that of the Cann at ten miles. Below 

 Chelmsford the Chelmer receives, at Little Baddow, two 

 affluents on opposite banks ; on the north or left bank one 

 from Holt's Chantry; on the south one from Preston, 

 Haningfield and Sandon ; and lower down the more important
