So tomorrow we disappear into the unknown. This account I am transmitting down the river by canoe, and it may be our last word to those who are interested in our fate. I have, according to our arrangement, addressed it to you, my dear Mr. McArdle, and I leave it to your discretion to delete, alter, or do what you like with it. From the assurance of Professor Challenger's manner--and in spite of the continued scepticism of Professor Summerlee--I have no doubt that our leader will make good his statement, and that we are really on the eve of some most remarkable experiences.
