That one I didn't get, but I won't ask . BTW Simon I just found your Lydham Heath thread, didn't know it was with you now. I think I saw it at Watford in 1997 or thereabouts, made a big impression.
Meanwhile back at the ranch, I got out the looking glass and read some instructions from the GWR Horse Dept that are reproduced in Tony Atkins' GWR Goods Cartage Vol. 1 (p76). Unfortunately there is no date.
"All requisitions for Provender must be made (through book no. 605) to the Horse Superintendent. They will be due at his office on each alternate Thursday [...] A supply for fourteen days ending on a Monday must be ordered each time, except for those Stations specially instructed to order weekly [...] The provender must be weighed on its receipt, and should a deficiency of any of the component parts be discovered, the circumstances must be at once reported. Great care must be taken to prevent waste and misappropriation."
So this suggests bi-weekly delivery as the norm, rather than weekly as stated elsewhere. The weighing is also interesting. How would that be done I wonder. Perhaps there would be scales at the stables.
As for misappropriation, yes that would be high crime wouldn't it! Never mind the Medellin Cartel, the infamous Farthing Hay & Fodder Ring strikes again!
