very much in favor of the indoor grown 

 plants, in many cases the increase be- 

 ing over 100 per cent. He added, 

 however, that while the results were 

 so strikingly in favor of growing 

 plants under glass the season through, 

 from the standpoint of the Department, 

 other considerations have to be kept 

 in mind, such as the relative cost of 

 the two methods, the production for 

 an entire season, the utilization >)f the 

 houses for other purposes, mainten- 

 ance, etc., in determining which 

 method to pursue. 



The speaker also used the chart to 

 illustrate his remarks upon the foiU- 

 lizer experiments which the Depart- 

 ment had carried on. He said that 

 this experiment had been planned to 

 bring out, if possible, the fact that 

 growers as a rule are too prone to 

 count on the \alue of commerciil fer- 

 tilizers in crop production, and he said 

 he believed the results of the experi- 

 ment would show that there is no fer- 

 tilizer so good, reliable and sure as 

 well decomposed organic manure — 

 something which could be secured 

 anywhere in the country. He said, 

 however, that experiments of this kind 

 to be conclusive, must be carried on 

 for a number of years in various 

 places. He cautioned the growers to 

 go slow on commercial fertilizers and 

 to put their faith and work into good 

 composts. 



He explained the work the Depart- 

 ment had been doing in the study of 

 hereditary tendencies in plants in so 

 far as same may affect continuous 

 vigor, healthfulness and yield. He 

 paid the question of whether there is 

 true bud variation was still an open 

 one, but that at the same time he did 

 not think the importance ancl value 

 of careful and rigid selection of stock 

 could be questioned. This the Depart- 

 ment has been doing and he stated it 

 was its intention to continue this selec- 

 tive work for several years until the 

 effects could be fully demonstrated. 



The speaker mentioned the work the 

 Department had been doing in the pro-

duction of new types by crossing aud 

 leferred to some of the crosses that 

 might be seen in the gi'eenhouses. 



He said that Prof. Norton, whose 

 talk was to follow his, would explain 

 in detail the fifth line of work, namely, 

 a study of fundamental questions ol 

 breeding, which work he stated had 

 been carried on by Prof. Norton be- 

 fore leaving the Department. 



Dr. Galloway now took up the sixth 

 line of work that the Department hail 

 been conducting, namely, an investiga- 

 tion of the diseases of carnations. 

 Among the diseases studied was the 

 wet stem rot, due to Rhizoctonia, 

 which, he stated, continues to be one 

 of the most serious diseases with 

 which the growers have to contend, 

 but that it could be controlled 

 by gi'owing the plants in well 

 drained and well aerated soil contain- 



ing plenty of lime, and by avoiding 

 mechanical injury to the plants. He 

 also mehtioned the dry stem rot, a dis- 

 ease caused by F^isarium — one of the 

 wilt fungi, and stated that the only 

 remedy for this disease was to use 

 sterilized soil and the liberal use of 

 acid phosphate. 



Two other diseases to which atten- 

 tion was called were the Macrosporium 

 spot, which he said could be pre- 

 vented by spraying with Bordeaux mix- 

 ture, and the Bacterial spot, a disease 

 occurring only in wet seasons on the 

 softer-loaved varieties. This disease 

 he stated might be controlled by light 

 syringing with a mixture of two paxts 

 commercial formaldehyde to 1000 parts 

 water. 



Dr. Galloway closed his remarks by 

 assuring the Society that the Depart- 

 ment was always at their service and 

 with an invitation to its members to 

 visit the Department greenhouses.
