four o'clock
-LSB- 23 -RSB- #Bolstering # : fights with pillows and bolsters . Then came the making up of parties for the journey home , and Tom joined a party who were to hire a coach , and post with four horses to Oxford . Then the last Saturday on which the Doctor came round to each form to give out the prizes , and hear the masters ' last report of how they and their charges had been conducting themselves ; and Tom , to his huge delight , was praised , and got his remove into the lower fourth , in which all his School-house friends were . On the next Tuesday morning , at four o'clock , hot coffee was going on in the housekeeper 's and matron 's rooms : boys wrapped in great-coats and mufflers were swallowing hasty mouthfuls , rushing about , tumbling over luggage , and asking questions all at once of the matron ; outside the School-gates were drawn up several chaises and the four-horse coach which Tom 's party had chartered , the post-boys -LSB- 24 -RSB- in their best jackets and breeches , and a cornopean -LSB- 25 -RSB- player , hired for the occasion , blowing away , `` A southerly wind and a cloudy day , '' waking all peaceful inhabitants half-way down the High Street . -LSB- 24 -RSB- #Post - boys # : the boys that drove the coach and the post-chaises . -LSB- 25 -RSB- #Cornopean # : a kind of trumpet . Every minute the bustle and hubbub increased ; porters staggered about with boxes and bags , the cornopean played louder .
