Nov., 1910.] A.NNUAL REPORTS. 29 



The total crop harvested from this orchard amounts to 550 barrels. The 

 apples from individual trees have all been oounted, bo that accurate data will 

 be yielded. 



To make this experiment thoroughly effective, we need to obtain tempera- 

 ture records al various points in the orchard, records of amount of rainfall, 

 and determinations of the moisture content of the soil in the various plots 

 throughout the growing season. This experiment is so promising al the present, 

 time that the writer feels that the expenditure of a considerable sum of money 

 in making these suggested determinations is very advisable. 



Plant Breeding Project. 



Included under this heading are the experiments in breeding of squashes, 

 muskmelons and carnations, together with the studies in the correlations 

 between fruit and foliage in the strawberry. The work under this head is 

 too voluminous to be readily summarized in a short report. Strong confirma- 

 tion has been obtained of the working of Mendel's law in hybrids between dif- 

 ferent well-marked types of squashes and muskmelons. Very complete sets 

 of data have been obtained as a result of these studies. Photographic records 

 have been carefully preserved and some valuable negatives made by the Lumiere 

 process of colored photography have been made showing not only the varying 

 proportions in form, but also the varying colois that were found in succeeding 

 generations of hybrids. 



The work in carnation breeding has been less systematic and has resolved 

 itself into two phases, first a search for pure types and, second, for valuable 

 variations that would be useful in commercial work. During the past season 

 pure color types were isolated and crosses made between them. These are 

 expected to show Mendelian proportions in the F :i generation. One valuable 

 new crimson carnation was discovered last season, and is being propagated 

 at the present time. 



The gathering of data connected with the correlation experiments has been 

 completed and is now being summarized. The work includes the records 

 on the fruit and foliage on 931 seedling strawberry plants. Each of these 

 plants was grown by the hill system. The berries were gathered separately, 

 each berry was weighed and its volume determined by a bouyancy test It 

 was also described as to form, color, embedment of seeds, character of base, 

 character of apex and color of seeds. Immediately after fruiting, all the 

 leaves from each plant were gathered, tied in bundles, and preserved in for- 

 malin. Twenty representative leaves chosen at random were measured 

 from each plant by means of a planimeter. It is expected that as a result of 

 these measurements it may be determined whether correlations exist between 

 the size of leaves and the size of fruits and the total amount of foliage and the 

 totabamount of fruit. 



Demonstrations. 



Demonstrations in orchard practice have been conducted at Manchester, 

 Goffstown and Warren. 



The first demonstration was given in the orchard of S. Corey and Son, 

 Manchester, X. H. It consisted in the pruning of apple trees. Mr. W. H.
