LIQUID MANURE FOR PLANTS UNDER GLASS. 



In the growth of plants in green houses and in the sitting-room, 

 the plant food in the limited amount of soils that can be used, often 

 becomes exhausted or rendered unavailable to the plant, and to over- 

 come the difficulty the application of liquid manures is resorted to 

 as the best means of giving the plants a rapid and vigorous growtii. 



The use of some liquid food is also necessitated by the small pots 

 that must be used to insure an abundance of bloom. 



To test a liquid plant food under the name of" Flora Vita" sent 

 for comparison with otber liquids, twenty-eight Bon Silene rosebushes 

 were selected. Fourteen of these were potted in soil made very light 

 with sand, and the remainder were put in a good rose soil, made of 

 roited turf and manure. 



These plants were divided into four lots of seven each. Two of 

 these lots, seven in sandy soil and seven in good soil, were watered 

 with a liquid manure made by placing stable manure in a tub and fill- 

 ing up with water, and the other two lots were watered with " Flora 

 Vita." The first liquid was diluted to the color of weak tea. 



RESULTS. 



The results of this experiment show : — 



First. That the liquid called " Flora Vita " gave as good growth 

 as the ordinary liquid manure. 



Second. That the roses potted in a soil composed largely of sand 

 made as good growth and gave more buds than those in soil with 

 little or no sand in it. 



In regard to the above liquid sent for trial we know nothing of its 

 composition ; but its liquid form and perfect solubility make it espec- 

 ially easy of application and free from the objections to other plant 

 foods for the sitting-room, since it is odorless and free from dust. 



We hope to give an analysis of " Flora Vita" in our next Bullitin. 



PROTECTING YOUNG TREES FROM MICE. 



In our last Bulletin we reported experiments made for the 

 purpose of finding some simple and harmless mixture which could be 

 used to hold Paris Green to the bark of young trees during the win-
