the same order is not maintained throughout both series, but such 

 could scarcely be expected. We should point out that the differences 

 in moisture-content between several of the varieties are within the 

 limits of error, and that the differences in hardiness for these varieties 

 as expressed by Mr. Macoun's list, are as yet somewhat indefinite, for 

 they have been determined from an extremely limited experience. 



From January 23rd, until the time of writing. May 18th, eight 

 fortnightly determinations of the moisture-content of these apple 

 twigs have been made. Instead of inserting all the data so obtained — 

 data, it may be said, which are in close accord with those of January 

 23rd, — I have prepared the following table, giving the averages of the 

 estimations made on the several dates upon which the twigs were 

 collected, and arranged in the order of their water-content: —

In all essential features this table confirms the results of the first 

 examination. The same six varieties are at the head of each list, 

 almost in the same order. In the last four, Hebble White now stands 

 No. 9, a position more in accord with Mr. Macoun's report. It is quite 

 probable that future experience may show the position of Boy's Delight 

 to be higher up in the scale of hardiness than that assigned to it this 

 year by Mr. Macoun. 



In the data furnished by this investigation extending over four 

 months, it would seem, therefore, that we have direct and definite 

 proof that there is distinct relationship between the moisture-content
