Abstract
IN an article on “Woods and Trees of Ireland,” in the Co. Louth Archaeological Journal for 1914, Prof. Augustine Henry states that in Ireland, as in Scandinavia, the climate prevailing in neolithic times was drier and warmer than that of to-day. Many facts are adduced in support of this improvement, which in Scandinavia amounted to an increase of 4° F. in the average annual temperature. The occurrence of this optimum cimatic period is confirmed by the fact that two species of elm in England are unable now to produce fertile seed.
