The third sound car was operated by Brother P. H. Davidson, the branch overseer. The penetrating sound of the machines drew the ire of the clergy, so that in 1936, at their urging, the government banned their use in public places. This ban was lifted in 1938, however, and the message of the Kingdom again began to bounce from the hills and roll through the valleys into the homes of the people.

In 1936 Thomas E. Banks, a pilgrim from the United States, made a visit to Jamaica. Commenting on the visit, Brother Davidson wrote in a letter to Brother Rutherford, dated May 4, 1936: “I have to thank you personally for your arrangement as president in sending Brother Banks to visit Jamaica. His visit has brought Brooklyn right into Jamaica and has supplied a long-felt desire to see things work here as in Brooklyn, hence our Bethel home, studies, service work, class visits, conventions and public witnessing have all been improved through the example and suggestions of Brother Banks.”
