I. QUEBEC, MONTREAL, AND OTTAWA.

THE total number of members travelling from the British Isles to attend the Toronto Meeting was 577. Of these 235 sailed from Liverpool on the Cunard R.M.S. Caronia on July 26, and of the rest smaller numbers sailed on the Canadian Pacific vessels Montrose, Montlaurier, and Melita, and the White Star vessel Megantic. Members on ships which proceeded to Montreal had the option of leaving them at Quebec and travelling to Montreal by train without additional charge.

As there were at least four clear days between arrival in Canada by the above ships and the opening of the Meeting in Toronto, arrangements were made for members who so desired to view Quebec, Montreal and Ottawa. A large body availed themselves of this opportunity, which was afforded through the generous co-operation of Government and University authorities with the local executive committee in Toronto, while the detailed arrangements were admirably carried out by Col. H. T. Bovey, of McGill University, Montreal, acting under the direction of Gen. Sir Arthur Currie, president of the University.

At QUEBEC on Saturday, August 2, members used the Jacques Cartier room at the Château Frontenac Hotel as a reception room, visited the Citadel and other points of historical interest in the city, and were entertained to tea at Spencerwood, the residence of the Lieutenant-Governor, Sir Louis P. Brodeur. The majority of the party proceeded the same evening to Montreal by special train on the Canadian National Railway, stopping en route for an inspection of the great bridge over the River St. Lawrence, above Quebec, and sleeping on the train.

At MONTREAL on Sunday and Monday, August 3 and 4, a reception room was opened in the Mount Royal Hotel. On Sunday the members were entertained to tea by Lord Atholstan. On Monday McGill University, Macdonald College (where luncheon was provided), and other educational institutions were visited; some members inspected the harbour (as guests of the Harbour Commission) and the St. Lawrence power plants, and carried out a botanical excursion in the vicinity of the city. On Monday night the majority proceeded by special C.N.R. train to OTTAWA; Tuesday morning, August 5, was spent in viewing the city. They were entertained to lunch by the Dominion Government, the Premier, Mr. McKenzie King, and many members of the Cabinet being present. The Premier welcomed the Association party and spoke at length on the many advantages of scientific research. The President (Sir Ernest Rutherford) replied. In the afternoon the train left for TORONTO, which was reached at 9 p.m.

II.—THE TRANSCONTINENTAL EXCURSION.1

The Transcontinental or Western Excursion after the Meeting, from Toronto to Vancouver and Victoria, B.C., and back, was taken by about

1 Thanks are due to Mr. W. H. Barker, who collected the notes from which this narrative is largely compiled, and to the following members who contributed them : Mr. H. Balfour, Mr. J. Bartholomew, Mrs. Bisbee, Prof. W. J. Dakin, Miss A. J. Davey, Dr. Gertrude Elles, Prof. W. T. Gordon, Prof. H. M. Hallsworth, Mr. H. T. Harris, Prof. J. W. McBain, Dr. Marion Newbigin, Prof. J. H. Priestley, Dr. A. B. Rendle, Miss Ridgeway, Mr. O. H. T. Rishbeth, Dr. G. Scott Robertson, Dr. F. C. Shrubsall, Prof. W. W. Watts.

360 persons, including 27 members of the International Mathematical Congress, which had been held in Toronto from August 12 to August 16. The members travelled in two special trains provided by the Canadian National Railway (Train A) and the Canadian Pacific Railway (Train B) respectively. Each train consisted of a baggage-car, car for the train staff, two dining-cars, eight standard sleeping-cars, and one observation car with sleeping compartments. The total length of each train was about 370 yards; this was increased, on the mountain section of the Canadian Pacific route, by the addition (kindly made by the railway company to both trains) of an open observation car. The trains travelled on the outward journey to Vancouver over the lines of the Canadian National Railway (excepting the section from North Bay to CochraneTimiskaming and Northern Ontario Railway); the return journey was made over the Canadian Pacific line. The rate for the journey to Vancouver and back, including sleeping accommodation, was fixed at $100, and table d'hôte breakfast, luncheon and dinner were provided in the diningcars at a total charge of $3 per day. The local committee in Toronto generously invited some of the members to make the journey as their guests, with a remission or reduction of the travel rate. Contributions toward the cost of the excursion were made by some of the provincial governments, and the most generous hospitality was enjoyed at every point, at the hands alike of public bodies and private individuals. The excursion was acknowledged by all who were privileged to take part in it as an unqualified success and a wonderful experience, and among all those who laboured to make it so the gratitude of the participants is especially due to Mr. D. B. Hanna, to whom, as chairman of the Finance and Transportation Committee in Toronto, fell the major part of the preliminary arrangements with the railway companies; to Dr. Willet G. Miller and Dean R. W. Brock (of the University of British Columbia), who shared the planning of the excursion and the conduct of the party; to Sir Robert Falconer, President of the University of Toronto, who also generously sacrificed his time to join the excursion, and to Prof. W. A. Parks, who represented the local executive on Train B. The staffs of the two trains were admirably efficient.

Sunday, August 17.-The trains, carrying the excursion party with the exception of the botanists and geologists referred to below, left the Union Station, TORONTO (254 ft.),2 in the evening.

Monday, August 18.-At TIMAGAMI (309 m., 986 ft.) a botanical party of some 25 members, who had left Toronto on August 14, joined the main body.

This party had reached Timagami in the morning of August 15, and were conveyed by steamer on the lake to Bear Island, the members being distributed for purposes of sleeping accommodation between Turner's Camp, Prof. Faull's laboratory on Bear Island, and Smith's Camp on Garden Island.

In the afternoon of August 14 a motor-launch conveyed the party to Timagami Island (north end), a trail being then followed for about four miles through virgin forest to the Wabikon Camp at the south of the Island. Chief Ranger Hyndson conducted the party. Interesting examples of old trees of both red and white pine were seen en route, as well as very characteristic undergrowth and fine examples of regeneration by deciduous trees after the coniferous forest had been destroyed by fire.

2 Distances of principal points are given in miles (m.) from the start of the excursion at Toronto throughout; elevations in feet above sea-level.

On Saturday, August 16, Sandy Inlet, to the north of Bear Island, was visited by motor-launch, where a number of interesting plants were seen, including marsh and aquatic plants in and near the Edye River, and a ground flora under a nearly pure stand of Banksian Pine to the north-west of the Inlet. In the evening many members of the party derived considerable pleasure from watching, and in some cases sharing in, a dance at Smith's Camp, in which the native Indians were prominent in square dances.

On Sunday, August 17, in the morning, the trail to the Fire Observation Post on Bear Island was thoroughly examined for plants, and some of the experimental cultures of rust fungi on spruce under field conditions, carried out by Prof. Faull and Mr. Watson, were also seen. In the afternoon the party proceeded by launch to Cochrane Island, and then by canoes propelled by boys from Mr. Cochrane's camp to the mainland, where a portage trail was followed to another inlet of the lake. The expedition throughout was exceedingly successful.

At COBALT (330 m., 969 ft.) a short stay permitted the town and district to be visited. The larger party inspected the Nipissing and the Cobalt Reduction Company's Mining Mills. Of recent years the output of silver has considerably decreased. Formerly some thirty mills employed over 4000 men. There are now approximately only ten mills, with little more than 1000 employees. New mines in the neighbourhood have absorbed a few hundreds of the unemployed. The arrangements made, whereby the party was conducted over the works in small groups, enabled the whole processes from crushing to refining the silver to be seen. In 1904, the year in which the first shipments were made, Cobalt produced 159 tons of ore carrying 5·34 per cent., or 1309 ounces, of silver per ton, and from 1904 to the end of 1923 about 343,895,780 ounces of silver, valued at $227,700,000. (For further details of the Cobalt area, see below, under date of August 19.)

An agricultural party was taken by motor-cars through some twelve miles of cultivated country, and rejoined the train at Liskeard, after visiting the Dominion Experimental Farm and Mr. A. J. Kennedy's Glengarry Stock Farm.

Both places are situated about four miles from New Liskeard on the South Clay Belt. The soil consists of alternate layers of light and dark medium loam. The light-coloured layers contain chalk and the darker layers have a high organic matter content. In spite of the high elevation and northern situation, agricultural efforts are meeting with considerable success. The long summer days make feasible the ripening of cereal crops within ninety days of sowing. The Government Experimental Farm is devoting special attention to investigation (a) as to types of crops which can be successfully grown, (b) suitable varieties of different crops-dates and rates of sowing and ripening, (c) the grading of stock for distribution to farmers.

Hay is the chief crop, but, owing to the supply being greater than the demand in recent years, a large proportion of the farmers are turning their attention to mixed farming. The usual rotation is:

(1) Oats, barley or wheat; (2) hay; (3) hay; (4) hoe-crop maize, sunflower for silage, potatoes, turnips, etc. The crops are sown during the last fortnight of May and the harvesting of the cereal crop begins in the last days of August. No artificial fertilisers are used. Stock-keeping is developing, particularly dairy stock of the Shorthorn and Friesian breeds. On Mr. Kennedy's farm, for example, there is a herd of 23 pure-bred Friesian cows from which milk is supplied to a creamery at New Liskeard, whence it is distributed as milk or butter in the mining towns of the neighbourhood. The development of stock is greatly needed in the Southern Clay Belt.

The experiments at the Experimental Farm have shown that flax-seed can be grown satisfactorily, and there are prospects for the development of a flax-fibre industry. There is an increasing demand from Southern Ontario for seed potatoes from this district.

Some idea of the development which has taken place may be gathered from the
