Describing his first view, he wrote: “Creeping with awe to the verge, I peered down into a large rent which had been made from bank to bank of the broad Zambezi, and saw that a stream of a thousand yards broad leaped down a hundred feet [30 m] and then became suddenly compressed into a space of fifteen to twenty yards. ”
Dalam melukiskan pandangan pertamanya, ia menulis, ” Sambil merayap kagum ke pinggirannya, saya melihat ke bawah ngarai yang terbentuk dari pinggir sungai ke pinggir Sungai Zambezi yang lebar, dan melihat bahwa aliran yang terentang ribuan meter jatuh sejauh tiga puluh meter lalu langsung terkompresi ke dalam ruang selebar lima belas sampai dua puluh meter. ”
