The collection contains
- Ascharjantu
- Shonku o Adim Manush
- Shonkur Parolokcharcha
- Professor Rondir Time Machine
The range of the stories span from the prehistorics to the future. Quite interestingly one of the stories actually starts with a failure of Shonku in devising a new instrument but the adventure remains supreme. Another contains an inkling of today's X-Men, maybe the visionary in Ray could also imagine the extended realms of imagination too. The shadow of a Conan Doyle theme and the afterlife becomes the theme of another exciting adventure. There is the prehistoric man and human evolution that is also investigated. A further appeal is the coloured photographs that had been a rarity in Ray classics. But altogether these are not so exciting as the older adventure. So for completing the collection this is a necessity but may not be satisfying to many.
