At the Havre Exhibition of the following year, 1868, a similar work was done; and in like manner, when a providential door was unexpectedly opened into the Land of the Inquisition, Mr. Muller promptly took measures to promote the circulation of the Word in Spain. In the streets of Madrid the open Bible was seen for the first time, and copies were sold at the rate of two hundred and fifty in an hour, so that the supply was not equal to the demand. The same facts were substantially repeated when free Italy furnished a field for sowing the seed of the Kingdom. This wide-awake servant of God watched the signs of the times and, while others slept, followed the Lord's signals of advance. One of the most fascinating features of the Narrative is found in the letters from his Bible distributors. It is interesting also to trace the story of the growth of the tract enterprise, until, in 1874, the circulation exceeded three and three-quarter millions, God in His faithfulness supplying abundant means.* * Narrative, IV. 244. The good thus effected by the distributors of evangelical literature must not be overlooked in this survey of the many useful agencies employed or assisted by Mr. Muller. To him the world was a field to be sown with the seed of the Kingdom, and opportunities were eagerly embraced for widely disseminating the truth. Tracts were liberally used, given away in large quantities at open-air services, fairs, races and steeplechases, and among spectators at public executions, or among passengers on board ships and railway trains, and by the way. Sometimes, at a single gathering of the multitudes, fifteen thousand were distributed judiciously and prayerfully, and this branch of the work has, during all these years, continued with undiminished fruitfulness to yield its harvest of good.
