or winter season. It is no unfrequent thing for the thermometer 
to mark 90° of heat in the shade during this period of intense 
sun-heat, and that the loose sand of the country should become 
proportionably hot will be readily conceived; and in this lies

Unless a proper degree of maturity is imparted to the bulbs, 
after the growing season, it is useless to hope for flowers ; their 
rudimental natures are not present, and, therefore, can never be 
seen in the perfect form desired. How contrary to this is the 
usual mode of management, where the pots are removed to aback 
shed, or some such place, cool and shaded, instead of receiving 
the ninety or hundred degrees of sun-lieat essential to their 
perfection !
