 INTRODUCTION.

My book is ready for the printer, and as I begin this preface my eye lights upon the crowd oi Russian peasants at work on the Neva under my windows. With pick and shovel they are letting the rays of the April sun into the great ice barrier which binds together the modern quays and the old granite fortress where lie the bones of the Romanoff Czars.

This barrier is already weakened ; it is widely decayed, in many places thin, and everywhere treacherous; but it is, as a whole, so broad, so crystallized about old boulders, so imbedded in shallows, so wedged into crannies on either shore, that it is a great danger. The waters from thou- sands of swollen streamlets above are pressing behind it; wreckage and refuse are piling up against it ; every one knows that it must yield. But there is danger that it may resist the pressure too long and break suddenly, wrenching even the granite quays from their foundations, bringing desolation to a vast population, and leaving, after the sub- sidence of the flood, a widespread residue of slime, a fer- tile breeding-bed for the germs of disease.

But the patient mujiks are doing the right thing. The barrier, exposed more and more to the warmth of spring by the scores of channels they are making, will break away gradually, and the river will flow on beneficent and beau- tiful.

My work in this book is like that of the Russian niiijik on the Neva. I simply try to aid in letting the light of historical truth into that decaying mass of outworn thought which attaches the modern world to mediaeval conceptions
