In 1898 Wragge began publishing "Wragge's Australian Weather Guide and Almanac", which contained not just meteorological information, but contributions on geology, bush craft, agriculture, mining, water supplies and postal information. In an effort to break the drought of 1902 he purchased a number of Stiger Votex Cannons, which were supposedly able to bring rain from the clouds. Test firings at Charleville on 26 September were unsuccessful. Wragge was not there to see the actual experiment, having left town after an argument with the local council. Today, two of the cannons are on display in Charleville.
