Sir Arthur Conan Doyle talks about the Boer Calvinists:

while to their corruption they added such crass ignorance that they argue in the published reports of the Volksraad debates that using dynamite bombs to bring down rain was firing at God, that it is impious to destroy locusts, that the word ‘participate’ should not be used because it is not in the Bible, and that postal pillar boxes are extravagant and effeminate.
