'Sir,' (it ran) –

'Upon arriving at Hengist Down you will put yourself at the disposal of Mr. Barforth, the Chief Engineer, who is in possession of my plans.

That proof you are destined to afford, and they to witness. As you descend in the lifts you will observe, presuming that you have the rare quality of observation, that you pass in succession the secondary chalk beds, the coal measures, some Devonian and Cambrian indications, and finally the granite, through which the greater part of our tunnel is conducted. The bottom is now covered with tarpaulin, which I order you not to tamper with, as any clumsy handling of the sensitive inner cuticle of the earth might bring about premature results.
