Plantations and Grounds 



Inadequate provision for labor made it necessary during 1927 



to confine lire work on the grounds largely to maintenance of ];i\ni> 

 and cultivated areas. The entire north addition of several acres, 

 fronting on i istern I'arkwan til! i 'mains in lurrovi now foi the 

 thirteenth year. Further development of the plantations, involv- 

 ing- numerous much needed additions and extensions of exhibition 

 material, must be postponed until more gardeners and laborers are 

 available. 



For maintenance, new development, and guard duty over 50 

 acres of intensely cultivated garden and lawn, including a nursery 

 and experimental plot, and also a range ot public conservatories. 

 educational greenhouses, and propagating houses we have only two 

 foremen gardeners and live gardeners, and a force of unskilled 

 laborers, varying from only four or five for most of the season, 

 to fourteen for about seventeen weeks (April 1 r -August 6). 



Every year sees a steady gain in the labelling of the collections. 

 Idpon this depends, in large measure, their educational value. De- 

 tails concerning our method of making labels have been supplied 

 to other institutions on request during the year.
