OPINIONS of the PRESS.

"The student of economic science and sociology will find this volume full of interesting material. . . The entire subject is of the profoundest interest, and an excellent purpose has been served by the publication of these papers in a single volume."-The Eagle (Brooklyn, N.Y.).

"Sir William Crookes's statistics seem to make good his alarmist statement."-British Weekly.

"The book is a useful one to all interested in the production of wheat both from the commercial and scientific points of view."-Knowledge.

"The appearance of the papers in this convenient form will be welcome to everyone who appreciates the importance of the problem."-Scotsman.

"In this bulky volume Sir William reproduces the gist of the sensational Bristol Address, and supplements it with carefully prepared answers to his chief critics and confirmatory chapters on the future wheat supply of the United States."-Morning Post.

"Sir William Crookes . . has propounded a problem which in the next century [written in 1899] is bound to engage the close attention not merely of agricultural experts, but of economists and statesmen."-Speaker.

Summary Results with young Store Cattle.-Better average gains were given by those wintered inside than than those wintered outside, but at the end of March practical valuers attached 30s. a head more value to those wintered outside, as they had better coats of hair and were more promising grazing cattle. Palm kernel meal gave better results than palm kernel cake with these young cattle, although the meal contained less than 2 per cent of The gains per week were quite satisfactory for such store cattle in winter, and (See Table III.). oil and the cake nearly 6 per cent. each lot came through the winter well.

Summary Results with Fattening Hoggs.-The sheep used were three-parts bred hoggs, and had been bred near Rothbury in 1915. All the lots made satisfactory gains, which indicated that palm kernel cake and palm kernel Again palm meal are suitable foods for fattening sheep. kernel meal gave a better result than palm kernel cake. (See Table IV.). ·

The fattening bullocks made average net gains of from £3 to £6 a head; their live weight value increased from fattening heifers made average net gains of 50s. to 64s. a 473. to 62s. a cwt. during the fattening period. The The net gains per head for the stirks varied from stores increased from ros. to 23s., and their value as head. 42s. 6d. a cwt. at the beginning of the winter to 48s. at the end. The fattening hoggs made net gains per head of from 39. to 5s., and improved in live weight value from 51. to 6 d. a lb. during the fattening period.

The Chairman of the Colonial Office Committee on Edible and Oil Producing Nuts and Seeds (Mr. A. D. Steel Maitland, M.P., Under Secretary of State for the Colonies) wrote on August 14, 1915, that his Committee would be very glad if the experiments now completed at Cockle Park, as well as other trials at Offerton Hall and

In 1913 over 234.000 tons of palm kernels were exported from British West Africa, of which over 181,000 tons went to Germany and about 40,000 tons to this country; and in 1912 over 50,000 tons of the same were exported from French West Africa, o which about 43,000 toos went to
