Meteor observers should note streaks at short intervals. For a ten-minute streak, diagrams showing positions every two minutes would be useful. Although past data is available, it is often rough and incomplete. More accurate records are needed to determine streak heights and atmospheric motion. Current data suggests streaks are 50-60 miles high and move over 100 miles per hour, similar to a destructive hurricane. This indicates upper air is influenced by faster currents than the lower atmosphere. If meteor observers carefully record streaks, they can better understand their behavior. Balloon data shows air movement at 10-15 miles altitude is east and southeast, matching most meteoric trains at 50-60 miles. W. F. Denning, Bristol, July 13. Climatic change: Prof. Penck argues that certain lakes, like Lake Chad, indicate increased precipitation during a "pluvial period." However, this is challenged by evidence suggesting recent outlet closure due to decreased rainfall. Prof. Penck's examples are flawed, as evidence points to drier periods in arid belts. The "pluvial period" may have existed outside glaciated regions. The Plumage Prohibition Bill aims to stop bird plumage trade. London is a major market, and the Bill passed second reading with a large majority. Opposition, including a non-scientific committee, may force modifications. Total prohibition is unlikely; a schedule would be introduced to protect endangered species. The trade's claim of job losses is unfounded, and the Bill's passage would likely lead to similar actions in Germany, ending the trade in Europe. Space and time are interdependent, as stated by Minkowski in 1908. His idea has not yet been realized.Meteor observers should note streaks at short intervals.
