Airdryand ground samples of 2-month-old guatemala grass (Tripsacum fasciculatum Trin) were utilized in a preliminary test to study the extraction time of cellulose in cupriethilene diamine, and to evaluate the precision of the method. The standard deviation and coefficient of variation observed were 2.87 and 3. 48 percent, respectively.
