Question: Which of the construction materials that St Nicholas was constructed with has a higher value on the Mohs scale? Passage:St Nicholas is constructed in flint, with some conglomerate and brick, and has limestone dressings. The roofs are tiled. Its plan consists of a nave, a chancel with a north vestry (previously a porch), and a west tower. The tower is wholly octagonal. In each face of the upper stage of the tower is a lancet, and there is another lancet on the west side at a lower level. The parapet is battlemented. The tower has a west doorway in Norman style, which has possibly been re-set from elsewhere in the church. It has scalloped capitals, and zig-zag decoration on the arch. Inside the upper part of the tower is a 17th-century dovecote lined with brick nesting boxes. On the south side, between the tower and the nave, is a brick stair turret. The nave windows have two lights with Decorated tracery. Between the windows on the south side is another Norman doorway, again with zig-zag decoration. The north and south walls of the chancel have two-light windows with Y-tracery, and three-light windows with Perpendicular tracery. The east window has five lights. The east gable is decorated with grotesque carvings, and above the east window is head-corbel and a blocked niche. The vestry has two-light north and south windows. In the north wall of the nave is an Early English doorway, with dog-tooth ornament. Around the church are stepped buttresses.

Question: How long did Reg Davies play for Leyton orient? Passage:On 21 November, Vale picked up their third league win of the campaign, beating lowly Barnsley 20 at Oakwell. Youth players continued to be drafted in as Vale finished the year with four straight league defeats, picking up injuries and sendings off along the way. In December, Hancock was sold to Ipswich Town for 10,000. A 21 victory over promotion-chasers Brentford on 2 January failed to spark a revival, partly due to the fact that the Bees were forced to play almost the entire match with ten players and an outside player in goal following an injury to Chic Brodie. Steele tried to play a settled team, but that proved to be as unsuccessful as when he switched the team round constantly. By the end of the month the club were bottom of the league and morale was low. In mid-February, the club four points short of safety, Steele left the club 'by mutual consent', as Jackie Mudie was appointed caretaker manager. Following a 40 hammering from Gillingham, Mudie signed veteran stopper Jimmy O'Neill from Darlington, and the former Ireland international seemed to improve the team, as just two defeats in eight games followed. Mudie instilled discipline into the team, and so was made manager on a permanent basis on 3 March. He then ensured Reg Davies was transferred to Leyton Orient. He tried and failed to re-sign Terry Harkin from Crewe Alexandra. One win in their final six games doomed the Vale to relegation, just as survival seemed possible. Only 3,521 witnessed a final day victory over Walsall.
