Address.
The concluding meeting of the Congress took place in the Physics Lecture Room on Monday, 1st February, at 8 p.m., when Mr. A. S.

Kenyon, engineer to the Victorian Commission of Waterways and Irrigation, delivered an address on “Problems of Irrigation in Victoria.” The Hon. G. M. Thomson presided, and referred to the lecturer as an anthropologist and an authority upon the stone age. Mr. Kenyon, in opening his address, referred to the significance of irrigation in Australia and in Victoria, where already one-fourth of the area was being irrigated. Irrigation schemes of a private nature were started in Victoria in the fifties of last century, but came to nothing. The matter was first taken up by the State in 1869, and had been continuously prosecuted ever since. A map was shown of the watershed of the Murray River, which covers a sixth of the whole continent, including the greater part of New South Wales and a considerable area of Queensland. The Murray's flow varied to a maximum 20 times as great as its minimum. One picture thrown on the screen showed the lecturer's assistant standing with the whole river passing between his legs. At other times that river provided 3,000 miles of navigable waterway. They now had 1,750,000 acre-feet in storage, and it was required to irrigate about a million acres. They were now completing a storage dam which would contain about 3,000,000 acre-feet, or two and a-half times as much as is in the Sydney Harbour. Half of this would go to Victoria and half to New South Wales. Other pictures followed of huge dams and irrigation works in different parts of Victoria. Then came detailed pictures showing the actual methods of applying the water to the land. The lecturer described the method of allotting water to the farmers able to profit by it. The amount of loss between the storage dams and the land on which it was used was as yet only a little less than 50 per cent. Methods of excavation were next illustrated and described, and many interesting engineering details given about the construction of weirs and dams. Water was not supplied to any district unless a considerable majority of the landholders there definitely asked for it. A series of pioneering pictures illustrated the rich and beautiful fruits grown with the aid of irrigation. Many pictures were shown of luxuriant lucerne, sugar beet, and orchards. They solved the labour problem, which was always very troublesome there, by making the holdings just of the size that could be managed by one industrious man. Pictures of different processes of handling drying raisins proved of considerabe interest. Most of the dried fruits are exported, the lecturer mentioned, under the Australian Dried Fruit Board. The next slides illustrated the canning industry. The latter portion of the lecture dealt with large systems for supplying water purely for domestic and stock purposes. A map was shown of a district which, valueless and abandoned before the coming of water, had now a capital value of over £50,000,000. In conclusion, recent great developments in wheat growing were described. In answer to the chairman, Mr. Kenyon said that the impregnation of the soil with salts was one of the biggest problems of irrigation. It was highly probable that it was on that account that the ancient irrigation systems of Mesopotamia had been abandoned. He stated that certain types of soil required tile drainage, but others did not. That drainage was very costly.

On the motion of Mr. Morgan, the lecturer was accorded a very hearty vote of thanks.
