Except for the last bar, it's really the same thing again. This piece was written for the Paris Conservatory for their annual contest in 1902. It's a great piece of music, but it also contains every difficulty the composer could think of. It should sound relaxed, resonant, and easy. The word stringendo in bar 18 means to go faster.
Fluency is more impressive than speed.
This gives you a natural stringendo. The composer does not tell us where to breathe and some phrases are too long for anyone to play on a single breath. Do the best you can, but breathe where necessary. Don't be afraid to break a slur, but experiment to find the most musical possibility. This is often after a long note, before a pickup, or on a bar line.
