Dr. Dudley's Geape 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 Rose 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. Zicovich, 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
