AGAIN this year, as two years ago, the organizers of the Marine and Small Craft Exhibition, which is held at the Agri- cultural Hall, Islington, very kindly gave the Institution a free site at the Exhi- bition. Here the Institution showed a Pulling and Sailing Life-boat of the self-righting type, a Caterpillar Launch- ing Tractor, a working model of a Life- boat rescue, and a number of other models. The Exhibition was open from 18th March to 4th April, and over £28 was collected..
