প্রজ্ঞা তার বাবার সাথে বুড়িগঙ্গা নদীতে নৌকায় করে বেড়াতে গেল। দাদা বাড়িতে যাওয়ার সময় নদীর পাড়ের যে ছবি তার মনে গেঁথে ছিল তার সঙ্গে এই মুহূর্তে দেখা চিত্রের সঙ্গে কোন মিল খুঁজে পেল না। নদীর কোন পাড় নেই, আছে অসংখ্য দালান কোঠা, দোকান পাট, শিল্প কারখানা। পানির রঙ একেবারেই কালাে, দুর্গন্ধময়। যে বিশুদ্ধ বাতাস নেবার উদ্দেশ্যে সে বের হয়েছিল, উল্টো দুর্গন্ধে তার দম বন্ধ হয়ে আসতে লাগলাে। প্রজ্ঞার খুব মন খারাপ হল। দেশের এত বড় নদীর এই দুরবস্থা।
