AbstractA ten–year campaign and a most important pioneer attempt to consolidate a metropolitan area under a single city—county government with a city–adn–county manager came finally to defeat in Alameda County in February.

The Russo-Mongolian Agreement of November 3, 1912, with its protocol; the Russo-Chinese Declaration of November 5, 1913, with the notes exchanged on that date; the Russo-Mongolian Railway Agreement of September 30, 1914, and the Tripartite Agreement between China, Russia, and Mongolia signed on June 7, 1915, together with the declaration of China and Russia, accompanying this last-mentioned document, are all printed in the Supplement to this number of the Journal and are deserving of more than a passing notice, for they undertake to define the relations of three great nations and recall historic events of considerable importance.

The recent Imperial rescript of the Chinese Government abolishing slavery within the empire is a document of unusual interest,1 and adds one more to the many evidences that have been given lately of great changes going on among this ancient people. The farreaching effects of this reform can hardly be estimated at present, but the proclamation of emancipation which is to be posted far and wide throughout the empire will be a charter of liberty to myriads of the down-trodden and oppressed, and will mark for them the upward turning of the way toward freedom and enlightenment.

Working trials is a canine discipline that originated from police and military dog work. One aspect of working trials competition is for a dog to "scale" a 6ft high wooden wall. Concern has been raised in other canine disciplines that landing forces after traversing jumps may lead to soft tissue injuries. There is a paucity of research into the impact of scale height on peak vertical landing force (PVF) in dogs participating in working trials. The aim of this work was to determine whether an alteration in scale height impacts PVF and apparent joint angulation on landing. Twenty-one dogs who regularly competed in working trials traversed the scale at three different heights; 6ft (full height), 5.5ft and 5ft. Changes in PVF, apparent carpal and shoulder joint angulation and duration of landing were analyzed using general linear mixed models. Dogs weighing >25 kg had greater PVF at 6ft than at 5ft (p 25 kg (p > 0.05). Apparent shoulder angle was not affected by scale height for any dogs (p > 0.05). There was considerable variation in the study population, but this research indicates that when the scale height was lowered to 5.5ft dogs had reduced PVF and less compressed joint angles on landing. When the scale height was lowered to 5ft they altered their traversing style and greater compression and increased PVF was seen. Evidence-based approaches to canine working trials are important to ensure minimum impacts on physical health and welfare of participating dogs, in terms of risk of injury in both competition and training. Based on these findings it is recommended that the maximum height of the scale is reviewed for training and competitive purposes, to ensure minimal impacts on the health of competing dogs, while maintaining the level of competitive challenge.

Working trials is a competitive canine discipline based on work undertaken by military and police dogs. A 9 ft long jump is a key component of the discipline. Research into landing forces and joint angulation in other canine disciplines has highlighted the potential for the occurrence of soft tissue injuries, predominantly in the front limbs. There is a paucity of work into the impact of spread/long jumps on joint angulation and peak vertical force (PVF) on landing, and limited research on working trials dogs generally. This study aimed to determine whether altering the length of the long jump impacted PVF and apparent joint angulation upon landing. 21 dogs regularly competing in working trials cleared the long jump at three lengths: 9 ft (full length), 8 ft, and 7 ft. The impact of altered long jump length on the PVF, apparent shoulder and carpus angulation, and duration of landing, were analysed using general linear mixed models. There was no significant relationship between the length of the long jump and PVF or joint angulation on landing (p > 0.05). Greatest joint compression was observed on landing after clearing 9 ft. Individual variability in landing joint angulation, PVF and force distribution of the left and right front limbs on landing was observed across all three experimental lengths. We recommend further research is undertaken to examine individual variability and the effect of training and experience in working trials participants, to provide evidence-based recommendations for training people and competing dogs in this discipline.
