 about 200 yards in length and of varying 

 width, but in no part more than twenty-

 water on the deep side is over ten feet, and may 

 be much deeper for all I know. The water 

 is generally quite clear, and no rain ever dirties

 spring, or springs at the bottom. There is no 

 visible outflow, but the water after reaching a

 probably finds its way into the common covered 

 drains of the field. There are two sorts of weed 

 growing naturally in this water, one is Chara 

 fcetida^ which carpets the bottom and is full of 

 fresh water shrimps, and the other is Potomogeton 

 Natans, a useless stringy thing, with leaves that 

 cover the surface after the middle of July, and 

 which has to be cut every summer in consequence.

 put in May 1887. In the autumn of 1888 

 the weight of these varied from four ounces 

 to three-quarters of a pound; in June 1889 

 those caught ran from eight ounces to fifteen 

 ounces ; in August one of one and a half
