"In explanation of the above table, it will be understood, that, in making the 

 estimate for cloudiness, the heavens are supposed to be divided into tenths. In 

 the journal entries, o signifies perfectly clear, and 10 signifies completely overcast. 

 The smallest amount of cloudiness is counted i, and the intermediate figures 

 between one and ten show the different gradations between these extremes in 

 tenths ; consequently the amount of sunshine is found by subtracting the figure 

 indicating cloudiness from 10. Thus the mean cloudiness for six months is found 

 to be, by the table, 4.46 : this, subtracted from 10, leaves 5.54 as the mean amount 

 of sunshine. In estimating cloudiness, all the different varieties of clouds, from 

 the lightest cirrus to the darkest nimbus, are included, and are particularly speci- 

 fied in the journal entry ; but it virould swell the tables inordinately to name them 

 all separately. 



" A critical examination of table No. II. will show several striking coincidences 

 between the rain-fall in June in each year and the state of the grape-crop in the 

 same year. It will be seen that the mean rain-fall for the month of June, for ten 

 years, was three inches and four hundredths (3.04). The rain-fall in June, 1859, 

 was but little more than one-half this average; and, in June i860 and 1861, it was 

 less than one-half this average. In each of these three years, the grape- crop 

 was very good, — not rot enough to be noticeable. In June, 1862, the rain-fall 

 was 4.69 inches ; which is nearly fifty per cent greater than the average for 

 ten years. It was in that year (1862) that the rot first made its appearance. The 

 crop in some vineyards was nearly destroyed ; in others, the damage was com- 

 paratively light. Taking the island as a whole, the yield was estimated at about 

 half a crop. From 1862 to 1866, the rain-fall in June did not in either of these 

 years come up to the June average. In each of these years, — say 1863, 1864, and 

 1865, — the grape-crop was very good : there was some rot, but not enough to in- 

 jure the crop materially ; and our grape-growers generally had settled down into
