'Owing to unfavorable weather conditions, this material was moved into a greenhouse shortlyafter itwas 

 cut, and the curing was finished there. This explains the unusual dryness of these saniples. They 

 are not to be considered field cured, and the percentage of moisture lost in air drying is therefore dis- 

 regarded.
