Before Gray left China Kendrick sent him a number of artifacts he had collected on the Pacific Northwest Coast, to be brought back to New England for a new museum (today the Peabody Essex Museum). Kendrick, having not received an accounting of Gray's business in Whampoa, sent a copy of his letter asking for such, but again Gray ignored it. On February 9, 1790, Gray left Whampoa. While waiting for a storm to pass Gray anchored "Columbia" less than from "Lady Washington", but avoided all contact and communication. On February 12, he left for Boston.
