The first part of this paper will give a brief introduction to maritime missiology, the second section will trace the beginnings of the Boston Seaman’s Friend Society in the nineteenth century and the third will focus on the Vineyard Haven branch of that work well into the twentieth century. Using source material from the American Seamen’s Friend Society - there is a 5,000 document collection of the ASFS papers in the G.W. Blunt White Library at Mystic Seaport, the Boston Seaman’s Friend Society - whose papers are mostly in the Congregational House on Beacon Hill in Boston, and other secondary works from the nineteenth and twentieth century. I am especially indebted to George Wiseman’s book, They Kept the Lower Lights Burning, Wiseman was the pastor of Trinity Methodist Episcopal Church in Oak Bluff during WWII and the son-in-law of Austin Tower. This presentation will look at the many facets that made up religious work among seafarers.

Growers of organic squash need effective ways to manage insect and disease problems. The squash bug (Anasa tristis) sucks sap, causing leaves to wilt and turn black. The squash vine borer (Melittia cucurbitae) can devastate winter squash plantings. Burrowing by larvae into the base of the stem causes yellowing and wilting. Organic insecticides are expensive, have limited efficacy, require many applications, and some kill beneficial as well as target insects.

Cucurbit crops, especially muskmelon and cucumber, attract cucumber beetles, which vector bacterial wilt: Erwinia tracheiphila, causing significant crop losses. High beetle densities are associated with high bacterial wilt incidence, which usually occurs during the first stages of plant establishment. Growers of organic muskmelon need effective ways to manage the cucumber beetle/bacterial wilt complex.
