Sheila contributed on-the-ground reporting from Palestine as Israeli settlements were expanded:

To the east of Jerusalem a much more serious venture has been taking shape in the form of the Ma’ale Adumim Block which is “targeted to become a major residential and industrial complex which will complete the encirclement of Jerusalem”, and which, when completed, “will extend the municipality eastward more than eight miles towards the floor of the Jordanian Valley” (see eye-witness account of Sheila Ryan and George Cavalletto, “Israeli Settlements in West Bank and Gaza”, as reproduced in a supplement to Palestine:, dated September, 1980, pp. 9-17; quotation from p. 10).
