named Glen Una in honour of Mrs. Hume, whose Christian 
name is Una. The proprietor, who is only twenty-four years of

Dr. Dudley’s Grape Farm. 
On the Almaden road, five miles from San Jose, Dr. J. P. 
Dudley has a beautiful place of 140 acres. Here he has prac¬ 
tised experimental agriculture and horticulture for many years, 
and at the same time has made a success of it from a business 
standpoint. His genius for experiments has led him to seek to 
obtain from the fruits which he grew a knowledge of their 
special qualities, which would render them of great value as life- 
sustaining elements. In pursuit of this knowledge he discovered 
that a particular kind of Grape, treated in a certain manner, and 
used as food, possessed high nutritive and medicinal properties. 
The particular kind of Grape is one having a peculiar degree of 
acidity of the Eose of Peru type, and the treatment to which it 
is subjected is the condensation of the juice by a process of 
evaporation. Thus is obtained in a convenient form an abundant 
supply of tartrate of potash, which, when taken into the stomach 
as food, is converted into an alkaline carbonate. To obtain the 
proper quantity of this tartrate the Grape must be grown on a 
soil having a clay base. The action of the alkaline carbonate 
upon the human system is said to be to dissolve the uric acid, 
and, therefore, the concretions, and to stimulate every gland to 
healthy action. The medicinal qualities of tartrate of potash 
have been long known to eminent physicians of this country and 
Europe, but the idea of obtaining it from the Grape in a form 
convenient for use, originated with Dr. Dudley, and his success 
is due to years of study and experimental work. 
Mr. Zicovich’s Vineyard. 
A. Zicovicli, who owns a 40-acre vineyard on the West 
Side, furnishes the following facts concerning wine-making:— 
The average crop ranges from three to five tons of Grapes an 
acre, the smaller and choicer varieties producing the former 
amount, and the commoner varieties the latter. In seasons 
when the rainfall is unusually abundant, and when it falls just
