        <p>黃州東南三十里為沙湖,亦曰螺師店。予買田其間,因往相田得疾。</p>
        <p>聞麻橋人龐安常善醫而聾。遂往求療。</p>
        <p>安常雖聾,而穎悟絕人,以紙畫字,書不數位,輒深了人意。</p>  
        <p>餘戲之曰:「餘以手為口,君以眼為耳,皆一時異人也。」</p>
        <p>疾愈,與之同遊清泉寺。</p>
        <p>寺在蘄水郭門外二里許,有王逸少洗筆泉,水極甘,下臨蘭溪,溪水西流。</p>
        <p>餘作歌雲:「山下蘭芽短浸溪,鬆間沙路淨無泥,蕭蕭暮雨子規啼。</p>
        <p>誰道人生無再少?君看流水尚能西,休將白髮唱黃雞。」</p>
        <p>是日劇飲而歸。</p>

        <p>歌管樓臺聲細細,鞦韆院落夜沉沉。</p>
