He says that his people would not bring the pay or anything else back.

When he sends to purchase ivory he gives the price to Arabs or Babisa, and they buy for him and conduct his business honestly; but his people, the Manganja, cannot be trusted: this shows a remarkable state of distrust, and, from previous information, it is probably true.
A party of the Arab Khambuiri's people went up lately to the Maravi country above this, and immediately west of Kirk's range, to purchase slaves: but they were attacked by the Maravi, and dispersed with slaughter: this makes Kimsusa's people afraid to venture there.

They had some quarrel with the Maravi also of their own, and no intercourse now took place.

A path further south was followed by Mponda lately, and great damage done, so it would not be wise to go on his footsteps.
Kimsusa said he would give me carriers to go up to the Maravi, but he wished to be prepaid: to this I agreed, but even then he could not prevail on anyone to go.

He then sent for an old Mobisa man, who has a village under him, and acknowledges Kimsusa's power.
