THE Ministry of Agriculture has recently issued Collection No. 1 of Leaflets on Fungus and other Diseases of Fruit Trees, price 1$. 6d. net. This collection contains a copy of each of the leaflets on the subject at present issued by the Ministry, and is bound up in portfolio form so that when a new leaflet or a revised edition of an old one is published an insertion or substitution can readily be made. Sectional vol. 1, which contained the same leaflets in a permanently bound form is, therefore, superseded, as it is hoped that the new arrangement will prove of greater convenience. Those who desire to receive a copy of each new or revised leaflet as it is issued, in order to keep their portfolio up to date, may do so on payment of a nominal annual registration fee. Full particulars concerning this matter may be obtained from the Secretary, Ministry of Agriculture and Fisheries, 10, Whitehall Place, London, S.W.I.
