Storing Potatoes with Lime. — Mr. James Knox writes from the Kingswood 
Reformatory, near Bristol ; “ Last year you published a letter regarding the non- 
extension of disease among potatoes when stored. In the hope that further 
attention may be paid to this by persons who, like myself, have charge of large 
institutions where economy is necessary, I write you this letter of ray experience 
in the matter, now that the digging season is approaching. Last autumn I had 
seventy-two sacks of potatoes ; these I collected in a heap, sprinkling each layer 
freely with lime, covering the whole with mould and a thatched roof. The conse- 
quence was I bad not a hundred bad potatoes, and we found that the action of the 
moisture of a bad potato on the lime was that a shell was formed round it similar 
to an egg-shell, and contagion avoided.” 
Combined Lime-kiln and Hot-water Apparatus. — Preparations are now 
being made to heat the whole of the forcing and other houses now in course of 
erection in the new kitchen-gardens at Hatfield, the seat of the Marquis of Salis- 
bury, on Cowan’s compensatory system, which consists in the combination of a 
lime-kiln and hot-water apparatus. A new kind of boiler is in course of manu- 
facture expressly for the purnose. Mr. Bennett had at one time decided to use 
either the Gold Medal or Witley Court boiler ; but, wishing to give lime-kiln 
heating every possible chance of success, a boiler, invented by Mr. Cowan, will be 
used for the purpose. 
How to Water Plants. — In reference to this matter Mr. Mechi says ; — 
“The sum of our experience in watering amounts to this — that thorough soaking 
of the ground two or three times a week is much better than the same amount of 
water applied in driblets daily, only sufficient to wet the upper surface, but not the 
under strata of earth contiguous to the roots. Cold spring water should, before 
applying it to a heated soil, be allowed to stand exposed to the sun and air for a 
few hours. The colder the water is, and the warmer the soil, so is the necessity of 
applying it in abundance ; for it is evident, though we cannot explain it, that the 
result produced upon plants by applying cold water to the soil, when at a high 
temperature, unless so copiously applied as to saturate the soil completely, is fatal 
to tender or weakly plants, and often less or more injurious to strong or healthy 
ones.” 
Effects of Vegetable Perfumes on Health. — An Italian professor has 
made some agreeable medical researches, resulting in the discovery tnat vegetable 
perfumes exercise a positively healthful influence on the atmosphere, converting its 
oxygen into ozone, and thus increasing its oxydizing influence. The essences found 
to develop a quantity of ozone are those of cherry, laurel, cloves, lavender, mint, 
juniper, lemon, fennel, and bergamot ; those that give it in smaller quantity are 
anise, nutmeg, and thyme. The flowers of the narcissus, hyacinth, mignonette, 
heliotropes, and lily of the valley, develop ozone in closed vessels. Flow'ers des- 
titute of perfume do not develop it, and those which have but slight perfume do not 
develop it only in small quantities. Reasoning from these facts, the professor 
recommends the cultivation of flowers in marshy districts, and in all places in- 
fested with animal emanations, on account of the powerful oxydizing mduence of 
ozone.
