I regret extremely that I did not subject some of my plants to experiments with this substance, which, however, I intend to do another season. Prof. Draper states - "when a solution of grape sugar, containing lime, is kept for sometime, the alkaline reaction of the lime, finally disappears through the formation of Glucic acid. It is soluble, deliquescent, of a sour taste, and yielding, for the most part, soluble salts." By applying, repeatedly, a solution to the plants in a soil nourished by lime glucic acid would probably be formed, and how far it may hold an important relation to the nutrition of or specific impression on the strawberry may then be determined.

It has also been stated that the value of the tannic acid application was dependant on the liquid and not on the tan, and that simple water was equally efficacious. Therefore manure water, poudrette water, and spring water, were essayed side and side, subject to the same exposure in every respect, and the results were carefully watched and recorded. The theory of the virtue of tannic acid was, in consequence, submitted to a careful, candid, and severe ordeal to determine the truth, and to furnish the best practical lesson for the cultivation of strawberries.

Manure water berries, exceeded in average size in the trial of Burr's Old Seedling. Spring water produced the greatest number of the largest fruit in the experiments with the Columbus. Poudrette water fruit gained in quantity over the spring water. The three substances held an inferior position to the tannic acid as to quantity.
