fore,seemed to be faulty and incompetent to set fruit at times, regardless ofthe kind and source of pollen. In 1913 only two berries were observed on the whole vine, and in 1914only a handful, less than a dozen berries, constituted the total crop offruit. These negative results pointed very strongly toward sterility of thevine. It seems that for some unknown reason the vine appeared tohave reverted all at once from a fruit-bearing vine to one that functionsessentially as a staminate vine. *In 1914 a Luola vine produced an exceedingly heavy crop of fruit, and among the manylarge clusters one was found composed of 35 berries. 14 The Bulletin In the spring of 1911 a layer of this vine was transferred to the Col-lege grounds in order to have the vine under better observation andalso to preserve the strain in case destruction should threaten the orig-inal vine. This precautionary measure was indeed a fortunate one, be-cause during the spring of 1916 the original vine was destroyed by fire.

The Bulletin 15 The layer that was transplanted to the vineyard grew well, and in1912 ten branches were bagged before any bnds had opened. Again,none of these flower clusters set fruit, and no fruit developed on theexposed branches of the vine. In 1913 ten branches with a total of twenty flower clusters were care-fully bagged, and this time eight of the ten bags contained some fruit.The whole vine had a fair sprinkling of fruit. In 1914 twenty branches with not less than a total of forty clusterswere bagged, and from each of these twenty bags some ripe fruit washarvested in the following September. The largest fruit cluster thatwas taken from these bags consisted of eight berries, while the largestcluster that was ever borne by the vine consisted of only ten berries. In 1915 ten more branches with no less than twenty flower clusterswe
