Series IV. Liquid manure Gruben-Dunger (Jauche) or feces 100 

 parts in 1,000 of water. 

 „ V. Same as IV. with 5 parts horn meal, and ^ part of 

 sulphate of ammonia. 



"These manures were added each week, and rain-water was applied on the 

 intervening days when necessary. 



The experiment was carried on from March 20 to November 9, or 

 234 days, the manure being added at intervals from April 24 to October 21, 

 on 26 occasions. The plants were repotted four times : on March 30 

 into 10 cm. pots, May 8 into 13 cm., June 3 into 18 cm., and July 28 into 

 22 cm. pots. 



The total amount of water utilised by each plant averaged about *76 

 litres per day. All were pinched back alike up to the June 10. 



Measurement of the height of the plants, the number of shoots, 

 average weight of five leaves from each, and the colour of the leaves are 

 given in the paper. The leaves of the unmanured plants were yellowish- 

 green, those of the manured specimens being darker green in the following 

 orders, series IV., V., II., III., the last being the darkest. 



The average widths and lengths of leaves were measured. The 

 greatest width and length among the indoor plants was seen in series II. , 

 the smallest length in series I., the least width in series IV. Only one 

 flower was allowed on each shoot, and the manuring was continued until 

 the colour of the bloom was beginning to appear (on October 21), after 

 which it was not repeated. 



The colour of the flowers of the manured plants was a darker rose 

 than that of the unmanured specimen » it was also duller in the case of 

 the indoor plants than the outdoor ones. 



The colour of the plants manured with the heavy dose of sulphate of 

 ammonia (series III.) was distinct from the rest, being a more bluish-rose 

 tint. Analyses were made to determine the dry matter and nitrogen 

 contents of the roots, stems, leaves and flowers, the results of which are 

 given in detail. 



The application of sulphate of ammonia seems beneficial, and the 

 Chrysanthemum is able to take up and make use of this substance even 

 when applied in such strong doses as in series III. — J. P.
