   “A manufacturer writes: We have had so much trouble with colored side leather and both colored and black cabrettas spewing within the past six or eight months that we are at our wits' end to overcome it. All of the tanners from whom we buy the stock contend that this is the best indication that all the animal fats have not been extracted from the leather.”
