An attempt was made on the chemical analysis of organic adhesive detritus-mainly composed of Diatomeae and Cyanophyceae (Table 1)-on gravels in Kazuno (Yamanashi prefecture) and Chikuma (Nagano prefecture) Rivers in 1951. The relations between the chemical composition, packed volume and dry weight were tabulated (Table 2). It was found that the detritus contains lipides abundantly, i.e. ca9% in organic fraction.
