The effect of the
Great Depression in West Cumberland was severe, and under the
Special Areas Act 1934 it was designated a "special area". Adams became in 1935 secretary to the new Cumberland Development Council. Another success was the re-opening of the Whitehaven coal mines in March 1937, again with help from the Nuffield Trust. They had been idle for a year, and it followed a
takeover.
Norman Nicholson, whose father was in the Chamber of Trade at
Millom and went to
Workington for one of Adams's meetings, wrote of "the almost fanatical persistence" shown by Adams, and the gradual arrival of factories and small businesses, some of them employing mostly unmarried girls and young women. Adams worked at 30 Roper Street, Whitehaven, with District Commissioner
George Mallaby as colleague in 1938–9, who was assigned to attracting industry. Mallaby described Adams as pugnacious and overwhelming voluble, redeemed by a lack of personal animus. The then chairman of the Council was Arthur Hibbert (1885–1947), who managed the Millom and Askan Iron and Steel Co. He was largely sidelined in meetings by the extensive reports from Adams. Mallaby mentions the geographer George Henry John Daysh (1901–1986) at Newcastle as someone who gained Adams's respect; he made a survey of West Cumberland. Of the Labour Party's distressed areas surveys that began in 1936, Linehan writes The idea for the survey originated at the annual conference, from a delegate in Whitehaven in West Cumberland, and it is difficult not to see the hand of Jack Adams in the exercise. It was somewhat typical of the political astuteness of Adams to, on the one hand, take funding from the
National Government's Special Areas fund, and then seek to undermine it by supporting a new survey that could only protest at the effectiveness of the Special Areas policy. Adams also became general manager of the West Cumberland Industrial Development Co. Ltd. Adams came to defer to his experience. The project was to build industrial facilities to let. In the case of the West Cumberland Silk Mills at Whitehaven, Adams made a protégé of
Nicholas Sekers, a refugee from
Hungary and the managing director from 1938. The outbreak of
World War II transformed the exploitation of the
natural resources of West Cumberland from uneconomic to strategically important. In wartime, Adams also had a hand in bringing Marchon Chemicals and its co-founder
Frank Schon from London to a Whitehaven factory. In 1943 Adams was awarded an
OBE. From 1943 to 1947 he held the office of Deputy Regional Controller of the
Board of Trade for Cumberland and
Westmorland Sub-region. In 1957 the
Encyclopædia Britannica wrote: By April 1955 approximately 60 industries, including engineering, tanning, leather, textile and chemical, had been introduced to west Cumberland, and work was available for 75,000 people. ==Later life==
