Question: In which country did the Essex v Northamptonshire match take place? Passage:The Essex v Northamptonshire match was played at Valentines Park, Ilford 17 to 20 May. Northamptonshire won the toss and decided to bat, scoring 215 all out with a top score of 49 by Vince Broderick while Essex's Test leg break and googly bowler Peter Smith took four for 65. By close of play on Saturday, Essex had replied to 170 for 4 with opener Chick Cray on 90 not out. He completed his century, exactly 100, on Monday morning and Essex went on to total 267 all out. Northamptonshire were 219 for 5 at the close on Monday evening with their veteran batsman John Timms on 90 not out. Timms was out for 112 on Tuesday morning and Peter Smith completed ten in the match by taking six for 84 in the Northamptonshire total of 291. Essex therefore needed 240 to win with ample time left on the final day. They had a good stand of 103 for the fourth wicket between Frank Vigar (60) and Len Clark (64) but spinners Broderick and Bertie Clarke kept picking up the wickets and Essex were still ten behind when the ninth went down. The last pair were captain Tom Pearce and wicketkeeper Tom Wade who managed to level the scores before Wade was bowled by Clarke to tie the match.
