On January 9, 1902, Dennis embarked on a sea journey from Asaba, travelling through Burutu and arriving in Lagos on January 14 to attend a Diocesan conference.
On January 25, Dennis began his return journey to Asaba, seeking to explore the Southern Nigerian region and its diverse languages while spreading the Gospel. He travelled by train to Ibadan, where Bishop Tugwell saw him off. He arrived in Ibadan at 5:00 pm and was warmly received by the Harding family, who arranged trustworthy carriers for his onward journey.
On January 28, Dennis commenced a 250-mile trek, spending his first night at Iroko, a small village. The following day, they departed Iroko at 6:00 am and arrived in Oyo that night. Dennis observed that Yoruba towns were larger and spaced farther apart than those in Iboland.
On February 3, they left Oyo around 2:00 pm and reached Ifiodan by 7:00 pm. While in Ilesha, Dennis learned about the area’s turbulent history of fighting and slave trading before British rule brought peace and began to support the town’s revival.
On February 10, they left Ilesha early and stopped at the village of Opolo for breakfast, where they discussed Christianity with the chief. In Iperindo, they spoke with local Mohammedans and the King about Jesus Christ, continuing their mission work.
On February 13, they trekked 20 miles through the forest to Isho/Uso and camped near a King who had previously welcomed Ogunbiyi. After crossing the River Ose, they camped at a site where Dennis enjoyed swimming. Continuing their journey on February 19, they walked 18 miles through several villages and noted similarities between Yoruba and Ibo languages, which encouraged them.
At Oliji, they received a warm welcome and gifts, including a goat, and Dennis shared his message. They then moved on quickly to Isele, where they encountered more Ibo speakers. That day, they covered 22 miles and, by dusk, were just 21 miles from reaching Asaba.
