Cottrell – Nov 18 /57
I send y ye follg calcn, wth refce / a pt wch may possy hve escapd yr attn
tho but when mentd y. will percve its importce
By inquiry in ye proper quartr I find yt ye GWR hve adopted ye follg scale of terml chges, varying accg to ye amt of freight.
. . . . . .
Let me supp. fr ye ske of argt that y are now payg the GWR 20,000£ per ann. for freight, & conseqly payg 9d per ton terml charges – If y. then undertake ^another set of works, in respect of wch y pay the GWR 10,000£ per ann. for freight,
your the terml charges sink to 6d per ton will be lessened by 3d a ton. But the ^most importt point is this, that this gain of 3d a ton will apply not only, to the ore raised at the new works, but to all the ore raised at Seend likewise, producing an indirect benefit of considble magntde
It is moreover possbl that this benefit may be doubld, viz. in case your
^payment payment were 19,000£ ^or 19,500£ for freight at your old wrks & 11,000£ at the new wrks this ^addition would raise the total amt two steps of the Scale, & give cause a gain of 6d a ton on the whole of the ore. I hope I have made my meaning ^clearly intelligible –
As I may perhaps have an opportunity of
spend consultg an Engineer abt the feasibilty of constructg a brch railw respectg wch I wrote to you on ye 12th inst, I shall be glad to hear fm y. on that subject
