The John Player League featuring
Essex v Leicestershire
In over 100 years of trying, Essex still have to win their first major competition. In 1976 they were runners-up in the John Player League to Kent with the same number of points. Last year again they were runners-up, pipped at the post again on equal points with the Champions. There is an added flavour to today's fixture as the team that robbed them of that honour are today's opponents.
PETER WALKER introduces the programme which includes news of today's other fixtures.

Tonight's film explores the animal community of a New England beaver pond. Few animals, other than man, alter their surroundings as much as the beaver. His dams create lakes and drown forests. As fast-flowing streams become still waters beavers provide homes and a living for many other creatures.
Spectacular photography takes us beneath the surface into a new world of hunters and hunted: hydras and waterfleas, nymphs of mayfly and dragonfly. It reveals the elaborate food chain that links them to the animals living on and around the water - both in summer's plenty and the harsh economy of winter. And then there are the beavers themselves, those industrious rodents upon whose efforts all ultimately depend. Narrated by John Hedges
