The present report is not as complete as was desired, owing' to tlie unavoidable delay experienced in fnlly equipping the de))aitnient ; but it is hoped that the near future will remove all hindrances, and assure the Lest facil- ities for making the series of observations mentioned in the first Inilletin issued by the Station. The tower room of one of the dormitories has been especially fitted u\) for the work, and a full set of Draper's Self -registering Instru- ments purchased, and every precaution taken to insure accuracy and detail in noting the various meteorological phenomena. The past month has been an exception and its paiallel unknown for years. There has been very little rain and snow, and the weath- er unusually mild. The table of hourly temperatures, and column of remarks, will together convey a general idea of the weather the past month. An explanation of the following pages is deen)ed unneces- sary as the headings themselves are considered sufficiently phiin. C. U. WARNER, Meteorologist. BAROMETER. KKDrCKI) TO FRKKZ1N(;. Ian. 7 A.

The average temperature and mean rehitive humidity were also below, the pre- vailing direction of the wind was the same, but a greater movement in miles was recorded the last P'ebruary. In the month of February, the last two years, .01 inch of water fell on 13 days. There was only 1 % difference in the mean cloudiness for the same periods, but the ozone was 15% higher the last month. Of the halos observed 86% were accompanied with rain or snow within twenty-four hours after the occurrence of the halo. On the evening of the 28th snow squalls were accompanied with frequent flashes of lightning. C. D. WARNER, Meteorologist. A. T.

T=trace. REMARKS. The mean temperature was about normal, the precipitation was greater than that of 1890. A heavy snow storm occurred on the 2d and 3d. Seven halos were observed, five of which were accompanied with precipitation within twenty-four hours after the occurrence of the halo. A cold wave occurred about the ■21st. Frogs were first heard on the 11th. High temperature, excessive sunshine, and a small amount of precipitation produced a marked change in vegeta- tion the last ten days ; grass is forward, fruit trees are putting forth blossoms. Some plowing and sowing has been done and early potatoes planted. C. D. WARNER, Meteorologist. A. T.

The weather duriug the month has been exceedingly changeable although the mean temperature was about normal, the first four days were warm and pleasant, but on the 5th frost occurred, a trace of snow fell and a thick coating of ice formed about the fountain on the col- lege grounds. On the morning of the 6th the ground was frozen to the depth of one-half inch, and the tender leaves of maple and chest- nut trees were destroyed. A heavy frost occurred on the 10th and tendei' plants were cut down, and fruit somewhat injured. The rain fall was below normal and grass on uplands suffered from drought ; but the rain whicli fell during the last few days of the month revived vegetation, and the condition of early crops is much improved. Six halos were observed, four were accompanied by precipitation within twenty-four hours after the occurrence of the halo. .C. D. WARNER, Meteorologist. A. T.

The rainfall was below the avei'age On the evening of the 13th, between 7 and 8 o'clock, a most mag- nificent auroral display was witnessed at the observatory ; for nearly- an hour the north was illumined with brilliant streaming light. This aurora is of special interest for such intense brilliancy of color is rarely seen in this part of the world, and while the display lasted, telephone and telegraph lines could be worked without the aid of batteries.

The temperature was slightly below normal, the weather was windy and disagreeably cool, and several frosts occurred during the first part of the month. A bi'illiant aurora was observed on the 18th which was followed by a sudden fall in temperature, heavy rains and snow, the latter being visible on the surrounding hills the 20th and 21st. The rain fall was much above normal. A record of official and local weather forecasts was begun at the observatory on January 1 of the present year, for the purpose of as- certaining the percentage of accuracy as regards this location ; these printed forecasts compared with the observatory records show 71% of the government and 80.6 "/(, of the local forecasts to have been correct. The following is a brief summary furnished b}' the New England Weathe'r Service which co-operates with this observatory : The weather for the month Avas intiuenced by the passage of seven cyclonic areas, or storuis, and six anticj'clonic areas, or areas of fair cool weather. They were not generall}' marked in energy nor of rapid movement. The temperature for the month was slightly below the normal ; the highest was a few degrees over 80 at most stations and occured on the 3 1 st ; the lowest was from 2.') to 80 and occurred on the 1 st. The precipitation was above the average and there was an im- usuall}' heavy excess of clouds and number of rainy days. Very heavy rain fell throughout all the central and western districts from the 20th to 23d. In the extreme west the temperature on the 20th was near the freezing point of water and considerable snow fell. • It is not thought that fruit was injured to any extent by the cold weather. The season is generally about one week behind the average at the end of the month, but with the present promise of warm weather it will rapidly recover. C. D. WARNER, Meteorologist. A. T.

REMARKS. , The weather was characterized by alternate hot and cool waves ; iu several iustauces the change of temperature took place in a shoi't space of time. On the 14th the mercury fell 20° in 20 minutes. The weather for the mouth, however, compares favorably with the coaresponding mouth of the preceding year, there being hut slight difference in the mean barometric pressure, humidity, and bright sunshine. The rainfall was slightly below normal, but the mean temperature was a little above normal. For Amherst, 83.;^% of the government forecasts and 70% of the local forecasts were found to be correct. The following is a summary furnished by the Director of the New England VVeathei' Service. The weather for the month of June, 1892, for Massachusetts as reported by tlie voluntary observers of the New England Weather Service, controlled by an unusually large number of cyclonic areas or storms, nearly all poorly defined and all, with one exception, passing to the north of New England. This northerly movement caused a prevalence of Southwest winds and consequently an abnor- mally warm month. The mean temperature at most stations was several degrees higher than usual while the range for the month was very large; th'e lowest occurred on the night of the lOth-llth, the mercury falling dangerously near the freezing point of water. A sharp frost was experienced on many lowlands, es|>ecially in the eastern sections ; gardens were injured in northeastern Massachu- setts and some cranberry bogs were badly injured on the Cape. The highest temperature was on the 14th, and, with the exception of on some of the coast islands, reached over 90°. Very heavy local storms occurred accompanied by severe and des- tructive lightning and hail. Many buildings were struck and some burned by lightning on the 2d, 14th and 17th. The house of Ebenezer Foster at Barre Plains village was struck by lightning during the storm of the 2nd and Mr. Foster who was sitting in the kitchen at the time was instantly killed. On the 14th the thunderstorm was accompanied by heav}' hail which did much damage in the upper Connecticut valley. At Turners Falls the average size of the large stones was 1 .y x \\ inches and the average weight was one-half ounce. The precipita- tion was above the normal except iu the southeastern sections : the local storms were not so severe there as in northern and western dis- tricts. The lack of sunshine during the last part of the month has delayed haying, and the season is slightly behind the average. C. D. WARNER, Meteorologist. FRANK L. WARREN, Assistant.

T=trace. REMARKS. The month was characterized by au excessive amount of heat, a small percentage of cloudiness and low humidity. Only nine times during the period of fifty-five years has the maximum temperature for July at Amherst reached 94° (the maximum for the present month), and only seven times has the minimum temperature reached 42°. Several severe thunder showers occurred during the latter part of the mouth and a number of brilliant auroras were observed. The rainfall was slightly below normal. Of the Washington forecasts 87 per cent, and of the local fore- casts 88.8 per cent, were correct for Amherst. The following summary is furnished by the Director of the New England Weather Service : The weather for Massachusetts for the month of July, 1892, was characterized by high and extreme ranges of temperature, an abun- dance of sunshine and a lack of pi'ecipitation. The weather was controlled by the passage of eight cyclonic and five anticyclonic areas, and while the latter were only about one-half the number of the former, they were of much greater energy and duration and their in- fluence prevailed during the greater part of the mouth. The local storms were not abundant but were of considerable energy, and some damage was done by wind and lightning. Unusually low temperatures occurred on the morning of the 4th and 17th, with the passage of the first .and third anticyclones, res- pectively. Slight frosts were reported in the northern New P^ngland states, although no damage has been reported in Massachusetts. From the 2nd to the 29th, excessively high temperatures prevailed over the entire state, although along the coast the heat of the 28th and 29t]i was tempered by an east wind. At Boston the mean tem- perature for the 25th, 26th and 27th was 83.6°, while at Amherst the mean for the 25th, 26th, 27th, 28th, 29th was 93.1°. The drought during the last part of the month was sharp and severe, although no serious damage is anticipated. It was broken by thunder showers on the 29th and by a steady northeast storm on the 31st and August 1st. At Springfield, Mass., the rainfall on the 29th was 2.00 inches, and at Worcester, Mflss., the fall on the same day was 1.49 inches; at Amherst, 1.1 inches. The aurora of the 16th was one of the most marked ever noticed in Massachusetts at this season of the year. It was preceded by an apparent lunar rainbow, and throughout its appearance was of rare beauty. C. D. WARNER, Meteorologist. FRANK L. WARREN, Assistant.

The month was characterized by heavy rainfalls ; the showers oc- curred mostly at night and were accompanied with heavy thunder and brilliant displays of lightning. The amount of precipitation was much above the average. The mean temperature was nearly two degrees above the normal for August, which was due largely to the high temperature for the first twenty-one days of the month. Of the Washington and local forecasts i>6.7 per cent, of each were found correct for Amherst. C. D. WARNER, Meteorologist. FRANK L. WARREN, Assistant. ^»t4^ 0^ CV»?t\<"^tV.

The month was characterized by pleasant weather. Only six days (luring the month were reported :is cloudy. The days were mostly warm and nights cool, but no frosts were observed till the morning of the 30th. The mean temperature was above normal. The rainfall was much below the average. A severe thunder storm occurred on the 2fith and several places were struck in Am- herst,but no great damage was done. Of the local forecasts 96.3 per cent, and of the Washington forecasts bd.G per cent, were true for Amherst. The following is a summary for the state, furnished bj^ the New England Weather Service : The month of September, 1892, will be remembered as unusually free from severe storms and being characterized by generally fair weather, pleasant for all out-door work or recreation. Only four cyclones passed near enough to New England to influence our weather and no West India hurricane reached our coast. Only five anti- cyclones spread acro!*s our district but they moved very slowly and so influenced our weather far more than the cyclones did. The daily temperature ranges were very strong, the days being generally warm and the nights cool, although only light frosts occurred in any part of Massachusetts. The precipitation was below the average and the number of rainy and cloudy days was unusually small. At Boston the total precipitation was 1.16 inch below the average for twenty- two years. At that station also the number of cloudless days was 21, partly cloudy days, 3 and cloudy days 6. A severe thunderstorm passed easterly across southern New England on the 24th and another on the 26th. Mr. Willard Nelson's house in South Monson was struck by lightning and considerable damage was done. The plastering in some of the rooms was torn off, in some cases within a few feet of people lying in bed, the casings and boards were ripped off and in one room all the tacks were taken out on one side and the carpet turned half across the floor. A good deal of damage is re- ported from Taunton, Mass. Many buildings were struck and sev- eral burned. No one was killed although several people had verj' narrow escapes. C. D.

T=trace. REMARKS. The month was characterized by a large amount of sunshine, low humidity, and very light rainfall — the latter being 3.25 inches below normal. The temperature was 2.5° above normal. The first frost of the mouth occurred on the 6th and the ground was slightly frozen on the morning of the 10th. Ninety-three and six tenths per cent, of the local forecasts and ninety-six and eight tenths per cent, of the Washington forecasts were found to be correct for Amherst. Following is a summary furnished by the New England Weather Service : The month of October, as observed in Massachusetts was un- usually warm and dry. The mean temperature at Boston was 1.2° above the average for 21 years. It was above the normal on the 1st, 4th, 7th to Jith, 11th, loth to 16th, 18 to 23d, and at or below the normal on the other days. The 14th was the warmest day in most districts, while at Boston it was 14° above the normal. Killing frosts have occurred at most stations but no general freeze has been ex- » perienced and many wild plants are green, and the mild weather has caused some to blossom much out of season. The precipitation was generally light and rain is greatly needed. Wells and streams are very low and the fall sown seed suffers con- siderably. At Boston the total rainfall was 1.97 inch belov the average for the month in other years. More than half of the whole amount recorded at that station fell in the storm of the 4th-5th. At Mansfield heavy rain fell with the passage of the thunder-storm on the 16th, but no dama'ie was done. Hail accompanied this shower at Salem in light quantities. The weather was conti oiled by the passage of six cyclones and the same number of anticyclones. Two of the cyclones passed easterly to the north of New England and the others passed across from west to east. This northerly trend of the storms, thus causing warm southerly wind during their passage, probably explains the high temperature. No \\ est India hurricane reached our coast during the month, although at least one passed up the Gulf Stream far out to sea. The number of rainy days was small and there was an excess of sunshine.

Snow appeared ou the surrouudiug hills on the oth ; the ground was frozen on the Gth for the first time ; the total snow fall was 4 1-2 inches but little remained ou the ground ai. the close of the month. Several gales of wiud occurred, the greatest damage ijeiug done on the lyth when Appletou Cabinet, at Amherst College was unroofed ; also a part of the Levi Dickinson box factory ; considerable damage was done in several other places along the Connecticut Valley. The rainfall was above normal and the temperature about 1° below. Both Washington and local forecasts were correct to l»6.6 per cent. The following summary is furnished by the New lingland Weather Service : The weather for Massachusetts for the month of November was iufluenced by the passage of uine cyclones and eight anticyclones. Of the cyclones live passed easterly lo the north of Massachusetts, two moved from south to north directly across the state, and two passed up our eastern coast. Most of the areas of high and low pressure were well marked and exerted a strong control on our weather and temperature. A sharp fall of pressure occurred on the 10th and again ou the IGth with a correspondingly sharp rise on the 17th. Peculiar fluctuations occurred at 5 p. m. on the 10th and between 6 and 8 r. m. of the J 8th. marking the central passage of the C3"clones of tliose dates. The mean temperature at Boston was about 1°.5 below^ the normal of the mouth. During the flrst half of the month the daily mean fluctuated above and below the normal, but from the 14th to 19th it was above, and from the 20th to the end of the mouth it was below. High temperatures occurred on the sth, 17th \iud ISth, while the minimum for the month was generally recorded on the 23d or 24th. Neither the daily nor the monthly ranges were large. This small range has been beneficial to grass and fall sown grains as the ground has not been covered by snow. From a trace to three inches of snow fell in some of the eastern counties on the oth, and about the same amount in the western part of the state -on the 9th-10th but the ground not being frozen in either case it quickly melted. From two to six inches fell again ou the 29th-.)0th, and as the ground was well frozen by the recent cold snap, it bids fair to remain for several days. The rain that was badly needed at the flrst of the month came in copious quantities and the ground is now well filled. The fall on the 9th, 10th and IGth was very heavy. The storm of the 18th gave extremely high winds in the Connecticut valley doing cousiderable damage. The storm of the 29th-30th was the most severe of the season. It came up our eastern coast and gave high northeasterly gales doing considerable damage to shipping and coast property. At 8 p. M. of the 29th the wind was blowing at the rate of 60 miles an hour at Block Island. C. D. WARNER, Meteorologist. FRANK L. WARREN, Assistant.

The mean temperature was slightly above normal. The rainfall, 2.51 inches below normal. Total snowfall for the mouth was three inches. There was only a trac^ of snow on the ground in sheltered places on the 15th and at the close of the month. The local forecast as com- pared at Amherst was correct to 90.5 percent; the Washington forecast 88.9 per cent. The following summary is furnished by the New England Weather Service : The weather in Massachusetts for the month of December was cold and dry ; fair weather has been in excess and the number of rainy days was less than usual. The air pressure was very near the normal with few rapid or marked changes. The amount of precipitation varied from .65 inch at Randolph, and 1.01 inch at Amherst to 1.70 at New Bedford, and 2 16 at Beverly Farms. At New Bedford the fall was 2.37 inches below the average for eighty years. At Boston it was 2.34 inches below ; while at the latter station the daily mean temperature was above the normal from the 7th to 17th and below from the 20th to 30th, and for the whole month the temperature averaged 3° per day below the average for 21 ^^ears. On the 24th the minimum was at zero while the maximum was onlj' 13° ; the mean for this day was 24° below the normal. At New Bedford the monthly temperature was nearly 4° below the normal for 81 years. The snow- fall was deficient, not exceeding more than one to two inches, and no more than a trace of snow and ice lay on the ground on the 15th or 31st, so the unusually low temperature from the 20th to 30th probably caused some damage to grass and grain. The Connecticut river was closed for navigation at Middletown, Conn., on the 23d. A flock of wild geese were seen flying south at New Bedford on the 24th. At Concord at 6.50 p. m. on the 27th a meteor was seen in the north at an altitude of 65°, disappearing near the horizon, and increasing in brightness ; it was more brilliaut than a star of the first magnitude.

A severe storm of wind occurred on the 20th. Eighteen inches of snow fell the 2-2nd ; the total amount for the month being 4:8f inches, which is greatly above normal. Six inches of snow was on the ground at the middle of the month ; 15 inches at its close. The government forecasts were correct for Amherst as follows : Boston 89.6 per cent. Washington 95.2 per cent. The foUowiug is furnished by the director of the New England Weather Service : The weather for the month througout the state was influenced by a large number of cyclones and anticyclones and they moved with unusual rapidity and energy ; there were ten cyclones and nine anti- cyclones ; the former predominated in force and time and caused large and very rapid changes in air pressure. It was a month of unusual disaster to shipping along our coast and a large number of lives were sacrificed to the waves. The storm of the 20th was most severe over western and northern New England and its equal has probably not been seen for years in this section. The amount of snowfall was not great in the south but it was accompanied by extremely low temperature and was driven by a high gale. A large number of cases of suffering and even death have been reported from this storm. It formed over the Lake re- gion and passed eastward directly across our district during the night of the 19th-20th, with a fall of pressure below 29.0 inches. The mean temperature was from 2° to 5*^ below the normal for the month. At Boston the daily mean was above the normal on the 1st to 3d, 6th, 7th and 10th to 16th and below on the other dates. The coldest day was the Sth with a mean of only n"^ above zero and the warmest was the 15th with a mean of 46^. The precipitation at this station was 2.65 inches above the normal. The total snowfall was oD inches ; it varied from 30 to over 50 inches throughout the state. From one to two or more feet lay on the ground through the greater part of the month thoroughly protecting all grass and grain crops. »»ii4 «* S.VMm^\.«.

T=U:iiT REMARKS. The mean temperature was about normal ; the coldest days were the 3d, 5th and 19th; the rainfall was slightly above the average while the snowfall was but 3 1-2 inches ; at the middle and close of the month the ground was unprotected by snow save in sheltered places ; a thunder storm accompanied by lightning occurred during the night of the 14th. Robins and bluebirds were seen on the J 7th. Boston and Washington forecasts were correct for Amherst 'J7.."> per cent, and 94.5 per cent, respectively. The following summary is furnished by the New England ^Yeath('r Service : The weather for»the month throughout jNIassachusetts was influenced by 9 cyclones and 8 anticyclones ; they moved with moderate rapidity and no very severe storms were noted ; several of the cyclones gen- erated secondaries off the coast. The air changes were not rapid with perhaps the exception of the storm which passed^ across New England from Southwest to Northeast during the ni;iht of the 14th and 15th. The amount of snowfall for the month was small and little re- mained on the ground on the 31st. The amount of snow was not sufficient to protect crops, but, owing to the equable temperature, it is thought little damage has been done. The frost is coming out of the ground gradually. The mean temperature was slightly below normal. At Boston, the coldest day was the 5th, with a mean of 17, and the highest daily mean was 48 on the 25th. At this station (Boston) the precipitation was 1.60 below normal. A thunder storm occurred on the night of the 14th and 15tli ; it was most severe in the southern pnrt of the state, but distant light- ning was seen in the northern districts. At Middleboro, lightning struck the Congregational Church, setting fire to the structure which was totall}' destroyed. A singular coincidence in connection with this fire is, that 51 years ago in the same month, a former church was. burned under the same conditions on the same site. C. I). WARNER, ^Meteorologist.

The weather for the month has been cold and backward, snow oc- curring as late as the 21st ; seven inches fell during the month. On the 26th the ground froze to the depth of one inch, but no serious damage was done to fruit buds already started. The rainfall was above normal and occurred on fifteen daj's : the total cloudiness was above the average : severe thunder showers were experienced the eighth ; the small amount of bright sunshine has retarded vegetation, little plowing has been done and only a few early vegetables planted. Telegraphic communication and arrangements for displaying flags have been completed. Telegrams from the Weather Bureau are re- ceived daily and recorded at the observatory, and weather signals are now displayed from a tall flag-staff on the tower. Washington and Boston forecasts were correct for Amherst as follows : 88,5 and 9-i. percent, respectively — they are based on fore- casts made for the twenty-four hours in advance. The following summary is furnished by the New England "Weather Service : The temperature during the greater part of the mouth was below normal, and the season backward in consequence. Rain fell on a number of days, but no severe storms, local or cyclonic, were noted. The rainfall, from the scattered reports that have been received at this early date, appears to be nearly the average. Thunderstorms were general in Massachusetts on the 4th and sth, Init were not of unusual severity. At Boston, the highest daily mean was o9 on the 29th. and the lowest daily mean, 31 on the 6th. The temperature was above nor- mal on the 1st, 2d, 4th, -Jth, Sth, 9th, 12th, 13th, i4th. 28th, 29lh, 30th, aud below on all the other days, with the exception of the 2.jth, when normal temperature was recorded. The rainfall at this station was 0.50 inch below the average, and amounted to 3.13 inches. Snow fell on the 6th and 7th, but none remained on the ground at 8 v. m. of the 8th, save in sheltered places and forests. C. D. WARNER, Meteorologist. FRANK L. AVARREN. Assistant.

T=trace. REMARKS. The month was cool and damp ; the temperature and rainfall were both slightly below normal, the mean cloudiness was above nor- mal, thunder and lightning occurred on several dates but no severe storms were noted ; the cool weather and deficiency in precipitation have affected the various crops. The following is furnished by the New England Service : June was below normal in both temperature and precipitation in nearly all portions of New England. In eastern Maine the deficiency in precipitation caused a drought to prevail and the hay crop will fall far below the average in consequence. At Boston the precipitation was 1.11 in. below normal and the temperature 38 degrees for the month, or an average of about one degree daily. The temperature was above normal on the 1st, 4th, 5th, 6th, 7th, 8th, 9th, 10th, 1 1th, 15th, 19th, 20th and 21st; it was below on all other dates. The warmest days were the 6th and 20th, with a mean of 82° ; the coolest the 17th when the average was 54*^. No high winds occurred during the month. Thunderstorms were noted in some portions of New England on the following dates : — 3rd, 4th, 6th, lOth, 11th, 12th, 14th, loth, 17th, l&th, 20th, 21st, 22(1, 24th, 25th and 30th. The storms of the 0th and 11th were most general, but were not severe in any locality. The other storms were moderate and experienced only in scattered portions of New England. An aurora of moderate brilliancy was observed on the 18th. C. D. WARNER, Meteorologist. FRANK L. WARREN, Assistant. »»v%* o"; t.v»?v>\Tt» V Nko»%»tt\i%^^ i,u«»5,'^, \i>>.%fc.

The amount of sunshine was greater and the average humidity much less than usual. Gales and thunderstorms were fre- quent but no great damage was done in the near vicinity of Amherst. The Washington and Boston forecasts were true for Amhergt, 88.3 and 90.2 per cent, respectively. The former is furnished by the New England Weather Service. The temperature during the mouth of .July averaged about normal, but the precipitation was considerably below the average not only in Massachusetts but throughout New England. At Boston the highest daily mean temperature occurred on the 16th with an average of 79° and the coolest day was the 24th when the mean was 63°. The month was remarkably clear ; only five cloud}' days were recorded at Boston. The thunderstorms were frequent but of short duration and no serious damage has been reported as yet to this office ; they occurred in some portion of Massachusetts on the following dates : 1, 3, 0, 7, 8, 17, 18, 19, 22, 23, 25, 26, 27. In some places wind did damage and several buildings were struck by lightning and burned, but no loss of life occurred although several were stunned by the shock experienced. The weather has been favorable to the hay crop but vegetation in general feels the need of rain. C. D. WARNER, Meteorologist. FRANK L. WARREN, Assistant. ?»^%S A.iiv^^ »xjivx:iM[A.i^i^, 2 HUMIDITY.

Of the cyclones three passed to the north of Massachusetts ; one passed easterly across the state, with little energy ; one passed up the east- ern coast asd two passed northerly across our western edge. The last named were the last three of the month and may all be designated as West India Hurricanes. The firstof the series passed to the north I well out to sea, striking the coast in the vicinity of Nova Scotia. It caused high winds and heavy rains on the coast on August 21st. Some damage was done both to shipping and to buildings and crops along the coast. The second of the three came up the Middle coast and onto the land near New York City on August 24th. This storm was accompanied by terrific winds and unusual heavy rainfall. Some damage was done to crops in the Connecticut valley by the storm and wind. The last storm ran onto the land near Savannah, S. C. doing terrible damage over the southern states. It passed to the north over New York state and western Massachusetts on the 29th, completing the havoc begun by the pi'eceding storm. Crops suffered severely throughout the Connecticut valley ; many fields of tobacco were almost wholly ruined ; much of the winter fruit was blown from the trees and not a little damage was done to shade and fruit trees within the storm area. At Amherst the wind pressure recorded was 37| pounds per square foot, or a velocity of 86^ miles per hour, the greatest ever observed at this place. This did more injury along the coast than the one before. A wind velocity of 70 miles an hour for a minute was recorded at Boston. The rainfall for the month was two inches above the average at ^ Boston, while the temperature was only slightly so. It was mostly above for the first ten days of the mouth, below for the next ten days, and above again at the last of the month. At Amherst the mean temperature was slightly above normal but the rainfall was nearly one inch below the general average. Light frosts were recorded on the 14th and loth although no serious damage was done. C. D. WARNER, Meteorologist. FRANK L. WARREN, Assistant.

September was cool and dry, the mean temperature was two degrees below normal and the rainfall was about an inch below the normal. The first frost of the season occurred-on the third, but no severe frosts were recorded dui'ing the month. The following is furnished by the New England Weather Service. The weather conditions during the month of September, 1893, ■were influenced by seven cyclones and nine anticyclones. Five of the cyclones passed north of us, down the St. Lawrence Valley, one across central New England from west to east and one up the coast east of us. The storms were not severe, with possibly the exception of the thunder storm of the 7th. A very heavy wind accompauied this storm and considerable damage was done in the eastern part of the state, and in the vicinity of Providence, R. I, At Boston the wind velocity increased in five minutes from 16 to 40 miles per hour, with a maximum velocity of 44 miles. The temperature during the month was considerably below the normal and the precipitation was also deficient. The storm of the 29th was accompanied by light snow in the Berkshire Hills. At Pittsfield the snow began at 7.40 a. m. and continued for about half an hour. The flakes were large, and rain fell at the same time. The driver of the Williamstown and Pittsfield stage states that in the vicinity of New Ashford the snow was about three inches deep. Of course it melted in a very short time. The last part of the month was unsettled, but no general storm occurred. The crops are about all harvested and are reported in good condition generally. C. D. WARNER, Meteorologist. FRANK L.

October was remarkable for a lai'ge amount of sunshine ; the temperature was much above the normal while the rainfall was below the average ; the number of rainy days was small, most of the pre- cipitation occurred on the 23 and 24. Gales were numerous ; the severest was experienced on the 14th; the wind velocity was much higher than usual for October. The following was furnished by the New England Weather Service : The weather during the month of October was influ- enced by seven cyclones and the same number of anticy- clones. Of the cyclones, four passed north of New England down the St. Lawrence Valley ; one developed over the State of Ohio, moved eastward and united with a storm from the Gulf of Mexico, then passed out to sea with little rain except in southern portions of New England ; one formed over the Gulf of Mexico, but dissipated over the Middle Atlantic Coast ; and one, the most severe of the month passed across New York State, then down the St. Sawrence, causing high southerly gales and rain in this part of the country. The temperature was from three to live degrees above normal and the precipitation was also above the avernge, except in eastern sec- tions where a slight deficiency has been reported. The most severe storm of the month occurred on the 14th, as a West India Hurricane, similar to those of August last, moved across Pennsylvania and New York. More damage was done in the south- ern part of the country than in this vicinity, but high gales prevailed during the day and the rainfall was heavy, especially in western New England. At Boston the maximum velocity of the wind was 49 miles. The timely warning given of the storm probably accounts for the small amount of damage done in New England. The frost held off remarkably. At Westbaro, Mass., the first killing frost occurred on the 17th, but the latter part of the month was cooler and frosts were more common. C. D. WARNER, Meteorologist. FRANK L.

T=trace. REMARKS. The temperature for November was about normal, the rainfall was below normal, the greatest quantity of rain fell on the 28th. The coldest day occurred on the 27th. The surrounding hills, on several occasions were covered with snow, but only an inappreciable amount was recorded at Amherst. A slight earthquake was felt on the 27th. The following was furnished by the New England Weather Service : The weather during the month of November was remarkably pleas- ant with temperature about normal. The maxima temperatures were recorded generally on the 3rd and the minima occurred in all districts on the morning of the 27th. The precipitation was considerably below the average. At Boston the deficiency amounted to 2.87 inches. Snow fell at a few scattered stations on the -Ith and light flurries also occurred on the 1.5th and 20th. In most cases it melted as it fell. The storms were not severe and no high gales have been reported. At Boston the maximum velocity was 39 miles per hour from the southeast on the 28th. An earthquake, although most severe in northern New England, was very generally felt at about noon on the 27th. The center of the disturbance appears to have been in the Province of Quebec. C. D.

The first part of the month was cold and the temperature was below the average, but during the last part the temperature was much above the normal. Many of the farmers have already put in their stock of ice. The latter is of good quality and from 8 to 12 inches thick. The following is furni-hed by the New England weather service : The weather for the month of December was influenced by the pas- sage of eleven cyclones or storm areas and nine anticyclones. Most of the former were fairly well defined ; the latter were generally accompanied by sharp cold waves. The mean temperature averaged over 2 degrees a day below the normal at Boston.

The month was unusually warm, the mean temperature being 5.4° above the normal. The precipitation was much below normal ; sev- eral cold waves and storms occurred during the month. The most severe storm came on the 29th and 3Uth, when ten inches of snow fell ; the wind blew at the rate of 52 miles per hour ; the pressure went down to 28.88° in a few hours, a fall of nearly an inch. The following is a summary of the weather in Massachusetts furnished by the New England Weather Service ; The weather for the month of January for Massachusetts was gen- erally warmer and drier than the normal. At the Boston Weather Bureau the daily mean temperature was nearly 5° higher than the normal for 21 years. At Somerset, according to the records given by Mr. Elisha Slade, it was 4.8° above the normal. At Boston the only days cooler than the normal were the 1st, !Jth, to 11th, and the 17th, while the othrrs were warmer than might be expected ; the 24th showed 23'' too warm. The nights were generally cold and there were at least two quite sharp cold waves on the 12th, 13th and 2!)tb. At Somerset the precipitation was 1.70 inches below the average and at Boston it was 1.20 inches below. The snowfall, until the last few days of the month, was especially light, and in all the eastern part of the state very little lay on the ground from the 1st to the 26th. A heavy fall came on that day and again on the 29th and .",0th which covers the ground at the end of the month to good depth. It is not thought that the weather changes during the month were great enough to injure fruit in any way, but grass and grain roots in most exposed places must have met with considerable damage. The last storm for the month was one of the most severe on record along the coast ; the pressure at Boston went down to 28.78 inches, a fall of 1 inch in 12 hours, and the wind blew at the rate of 51 miles an hour from the northeast.

The weather for the month of February in Massachusetts was colder than the average for other years, and it was drier in the cen- tral and western part and wetter on the southeastern coast. At Woods HoU the precipitation for the month was about three-fourths inch above the average amount for this month, but at Boston, Fitch- burg and Somerset it was from half an inch to one and one-half inches less. At Springfield, the fall just equalled the normal. Cold spells prevailed on the 6th, ]7th, 24th and 25lh. The lowest minimum temperature occurred at most places on the morning of the 25th and was the lowest recorded for a long time at a good many stations ; but the coldest day by far was the 24th. The mean tem- perature for the day must have been below zero in all sections of the state, while a great many observers report the highest for the day, several degrees below zero. At Boston, the temperature was at zero at noon, but ran up to 0° above before night ; the mean for the day here was a fraction of a degree below zeio. The strong wind made the cold all the more iiitente. The ground was well covered by snow most of the month and it is not anticipated that any material damage has been done to crops or fruit trees. A fine auroral display was observed on the 23rd which by many is connected with the cold weather following. Thunder and lightning- was observed in the eastern part of the state from 10 to 11 a. m. of the 10th. The mean temperature for the month was slightly above and the precipitation very much below normal,, but the snowfall was greatly above the average for February. The coldest days were the 6th, 14th, H)th, )7th, 24th and 2.')th — on the last date the mercury regis- tering I 7"' degrees below zero. The largest fall of snow occurred on the 14th. February 23d a remarkable display of the Aurora Borealis was observed. A band of greenish-white light extended rainbow-like across the northern portion of the heavens from east to west, about 15'^ above the horizon ; this soon changed into abroad band of red light and from all parts of the heavens flashes and waves of variously colored light shot brilliant rays upward, forming about the zenith a quivering canopy of flame, the most brilliant display lasting about one minute. As this aurora comprehended most of the peculiarities of other varieties, it might be called a complete aurora. Blue birds appeared at the end of the month. C. D. WARNER, Meteorologist. FRANK L.

The warm weather during the tirst part of the month started the buds so that man}' were injured during the cold weather which followed, peach buds espec- ially. The ground is nearly settled and plowing is being done. The most brilliant aurora ever witnessed in Massachusetts was seen on the 30th inst. The following is furnished by the N. E. Weather Service : The weather of the past month has been abnormal in many ways. Never before at Boston, in the history of the weather bureau, has the mean temperature for the month of March been so high ; never has the mean for the three consecutive warmest days, or the mean for any single day been so great, and never has the total precipita- tion for the month been so small. The daily mean temperature for the month was 13'' above the normal, being 27^ above on the 19th. It was above the normal from the 1st to 23d inclusive, below on the 24th, above on the 25th, below on the 26th to 3Uth, and above on 31sl. On the 27th the tempera- ture fell to 20° at Boston and did not rise above 32"^ at any time during the day ; the mean for this day was 12" below the normal. The precipitation was less than one inch and was almost three and one-half inches below the usual amount for the month. The wind movement was unusually small, and the maximum for the month only 36 miles an hour, occurring on the 16th from the west. Eleven cyclonic and nine anticyclonic areas influenced our weather for the month. Eight of the former passed to the north of Massa- chusetts and two passed over our district in the form of a long, low, pressure trough. The northerly movement of the storm areas, thus giving us prevailing southerly winds, explains the high temperature for the month. The cold wave of the 26th was widespread, and in other sections very injurious. It came with the eighth high pressure area for the month which spread from the far Northwest over the entire central and eastern parts of the country on the 26th and 2Sth. On the morning of the 27th the freezing line had moved south to the Gulf of Mexico, the mercury indicating only 18" at Atlanta, Ga., and 32'* at Jacksonville, Fla. Reports indicate that in Massachusetts the fruit buds were not advanced enough to be injured by this cold snap except possibly peaches ; these were severely injured during the cold spell in February and were undoubted further damaged this month. The aurora of the 30th was one of the most brilliant ever witnessed in eastern Massachusetts. The streamers covered the entire heavens most of the time from S to 9 p. m. C. D. WARNER, Meteorologist.

T=trace. REMARKS. The month has been unusually warm and dry- The temperature was about 3° above normal while the precipitation measured about one-half the average for April for the period of sixty years. Vegetation is forward and fruit trees, with the exception of peach trees, Indicate an abundant harvest. The last frost was recorded on the seventeenth. Farmers are ahead with their work. The following report is furnished by the New England Weather Service : The weather for April has been very favorable for all farm work and for seeding. The month as a whole has been warm with plenty of sunshine, while the precipitation has been below the usual amount except on the immediate coast. Five cyclonic and six anticyclonic areas influenced the weather. Of the former two passed eastward to the north of New England, causing southerly winds and warm rains ; one moved across our dis- trict from west to east with general rains, and two passed easterly to the south of us, one moving directly east onto the ocean and the other curving northerly up our seaboard. Both of the last named gave northerly winds and snow. The amount of snow was least in the western section and heaviest along the coast ; it came as a sur- prise but probably did much more good than harm, as it supplied much needed moisture. At the end of the month, there is a general complaint of the dryness of the ground and of the lack of water in springs and wells. There is a deficiency of several inches in the rainfall since the first of January in the greater part of the state. In eastern Maine this deficiency amounts to ten inches, but it is much less in Massachusetts. The nights have been cool with frost during the last week. This has served to hold the fruit buds somewhat in check, notwithstanding the warm sunshiny days, and it is hoped they will be able to stand any frost that is generally expected in May. It is generally reported that peaches were injured to the extent of G0% to 80% by the cold wave in February, but other fruits now promise very well. A report comes from Grafton, Mass. of raspberry bushes being badly winter killed. At the end of the month the season, both in the appearance of vegetation and the farm work on the land is fully ten days ahead of the average. C. D. WARNER, Meteorologist. FRANK L. WARREN, Assistant.

The temperature for the month was about 3° above the normal, the highest means occurring on the 11th, 16th, 17th, 18th, and 23d. The rainfall was six tenths of an inch below the normal and occurred mostly on the 3d, 4th, and 30th ; on the last date a heavy thunder shower was recorded. The middle of the month was dry and hot. The following was furnished bv the New England weather service : The controlling agent of the weather for Massachusetts for the month of June was an area of high barometric pressure which moved from the central Mississippi valley to the southern Atlantic coast on the Sth, then held there, shifting slightly back and forth, till near the end of the month. It appeared to deflect the storms northward, and there was a drifting line of low pressure areas moving eastward to the north of us. With the adjustment of the air pressure the pre- vailing winds were of course from the south and they came across our section generally dry and hot with but few clouds to obstruct the scorching rays of the sun. On two occasions, the 24th and 29th, small antic^'clones spread across northern New England, causing cool northeasterly winds and clouds along the coast, but the relief was only temporary. At Boston the mean temperature averaged nearly 3° a day above the normal while at Fitchburg it was nearly 2° above. The mean day temperatures averaged much higher comparativeh', because for the most part the clear sky allowed free radiation of heat from the ground at night and a consequent lowering of the night air temperatures — holding the mean for the day down near the nor- mal. Tiie precipitation at Fitchburg was 1.00 inch and was 1.75 inches below the usual amount. At Boston the total was only .80 inch and was 2.42 less than usual. At Concord, Mass., only about half an inch fell. Local showers prevailed in the western counties and in some parts ot the eastern giving some relief to the crops, but in other places especially in the east almost no rain has fallen for weeks and everything is suffering.

The weather has been exceptionally warm and dry, the mean tem- perature was about 5° above the normal, while the mean precipita- tion was nearly three inches below the normal for a period of sixty years. Very little rain fell before the 22d and crops and vegetation suffered not a little. The following is furnished by the N. E. W. Service : The weather for New England for the month of July, 1894, was influenced by the passage of six cyclonic and the same number of anticyclonic areas. All but one of the former passed easterly to the north of Massachusetts, and most of them well over Canada giving us only their southerly edge and accompanying thunderstorms. One storm passed over our district from west to east and then moved southeasterly off the coast. At Boston the temperature was above the normal for the first few days of the month, then varied above and below until the 24th at which date it was one degree below for the month as a whole ; on the 17th the temperature averaged 11 "^ below the normal. From the 24th to 31st the heat was very great and averaged 79° a day or almost 8.0'' a day above the normal ; so, for the mouth as a whole the mean temperature has been nearly 2° a day warmer than usual. Since January 1st the excess of temperature at this station has been 594", or about 2.8° per day warmer that the average for 24 years. The precipitation has been .50 inch below tiie average for the month at Boston, and for the seven months since January 1st there has been a deficiency of 7.32 inches. The total rain at this station for July was 3.09 inches, 2.80 inches of which fell since the 21st. The total rainfall between May 24th and July 20th was less than the amount from July 21st to 31st. This rain ended a very severe and prolonged drought over the northeastern part of the state, which has done a great amount of damage to all ciops. Corn withstood it better than other crops but that has suffered quite a good deal. In the southeastern part of the state on the Cape the drought continues and is almost unprecedented in length and severity. In Western Massachusetts much more rain fell during the first part of the month and crops have suffered little if any until the present time when a rain would be ver}' beneficial. C. D.

The month has been extremely dry, only thirty-one one-hun- dredths of an inch of rain having fallen. The normal precipitation for August for the last fifty-eight years is 4.34 inches ; therefore, the past month shows a deficiency of over four inches of rainfall. This lack of rain has caused great damage to farmers, streams and wells are dry and a water famine almost prevails. The temperature was about normal. On the 22d a light frost occurred in the lowlands but little damage was done to vegetation. The following is furnished by the N. E. Weather Service: The month of August, just past, was very nearly normal in tem- perature. No extremely high readings were recorded and cool nights were the rule. Frost has been reported from various parts of the State on the morning of the 22d, but no damage was done to vege- tation. At Bostou the minimum was 47*^ on that morning which is as low a reading as has ever been recorded during the month of August for 24 years at that station. At Concord, the temperature fell to 38" and light frost occurred in exposed places. The rainfall was deficient throughout the State ; ponds, wells, etc. are very low. At Boston more than two-thirds of the rainfall of the month fell in less than four hours on the 20th. During that storm, which was accompanied by thunder and lightning, 0.50 inch fell in five minutes, the largest amount that has ever been recorded at Bos- ton in that space of time since records have been kept. The storm was very local and did not extend many miles from the city. As compared with the previous month (July) a decidedly pleasant change was noticeable. C. D. WARNER, Meteorologist. FRANK L.

All precipitation occurred between the 6th and 20th inclusive. The greatest quantity of rain fell on the 19th and 20th, 2.33 inches being recorded. But little frost occurred during the month and the last ten days were generally fair and warm. The following is furnished by the New England Weather Service : The excessive drought which had prevailed throughout Massachu- setts in June continued in September until the 19th-20th when from one to two inches of rain came. The wells and springs were lower than ever before known in many sections and though this rain was not sufficient to fill them up, it wet the top of the ground and filled up streams a little. Late forage crops have been greatly benefited, the ground has been put in condition for fall plowing, and grass and grain seed has started nicely. Pastures and fields have started into new life and look quite green, and fall feed will be generally good. The month as a whole has been warmer than the normal ; at Boston the excess amounts to slightly over two degrees a day. The frosts of the 2r)th and 27th did considerable damage in all \ovr lands, though a great deal of the corn had been cut, and other crops that might have been injured, gathered. At Boston the rainfall for the month was about one inch less than the normal amount. Nearly two-thirds of the whole amount for the month came during the afternoon and night of the 19th. A very heavy thunder storm passed across the northern part of the state on the 10th doing considerable damage, by lightning, water and wind. At Wincliendon almost four inches of rain fell on that date, more than one inch coming in twenty minutes.

The weather for Massachusetts in the month of October was warmer than usual with about the average amount of precipitation. There was plenty of sunshine and in most places no weather cold enough to injure apples or hard}' garden vegetables. On the whole, the month has been very favorable for the maturing of late fruits and crops, and for harvesting and fall plowing and seeding. At Boston the mean temperature averaged nearly 8'' a day above the normal. The lowest temperature recorded was 38° on the 15th and 16th, and the highest was TG'* on the 20th. The precipitation there was .83 inches above the usual amount for the month and was well distri- buted. At Amherst the mean temperature was above the normal and the rainfall was about an inch above the average for 59 years. On the 16th ice formed, and the ground froze slightly in places. No great damage has been experienced fiom severe frosts, and gener- ally speaking the weather has been very favorable for farming. At Boston the accumulation of tempeiature since January 1st is 133^ in excess of the usual amount ; or in other words, the j^ear so far has averaged nearly 2.5" a day warmer than the normal for 20 years. There is a deficiency of very nearly 9 inches in precipitation at this station since Januar}' 1st; and if predictions could be made from averages we might look for considerable cold weather and snow for the next two months. The rainfall is still insufficient for wells and springs, although grass roots and newly seeded fields are having enough moisture for rapid development. The month has been favorable for the grass prospects in 1895. Eight cyclones and six anticyclones influenced the weather, most of the areas of fair and foul weather being of marked development and moving rapidly. Four of the cyclonic areas passed easterly to the north of New England, one passed across our district from west to east, one moved up the eastern coast, one moved south of us and one crossed New England from south to north. The last named was a West India hurricane, having moved up the Atlantic coast from the Mexican gulf. It gave heavy rainfall and high gales. C. D. WARNER, Meteorologist. FRANK L. WARREN, Assistant.

REMARKS. The following is furnished by the New England weather Service. Weather for November in Massachusetts. The weather in Massa- chusetts for the month of November was cold and dry. At Boston the mean temperature was 4.5° a day below the normal. It was above the normal for the first four days with an accumulated excess of 28°. From that date to the end of the month there was a daily deficiency, except on the 16th, 17th, 22d and 23d, with an ac- cumulated deficiency of 135°, or 163° in 26 days. The 29th and 30th were the coldest days of the mouth with a mean of 22° and 23° respectively. The strong wind on the 29th with the low temperature made it one of the coldest and most disagreeable Thanksgiving days since 1873, when a temperature of 11° was recorded. The low temperature of this month has reduced the accumulated excess for the year to about 600°. There was a great excess of stormy and cloudy weather, yet at Boston the precipitation was 1.60 inches less than the usual amount for the month. Rain or snow fell to an appreciable amount on 14 days, while a trace came on four other days. The storm of the 5th was the most severe of the month in amount of damage done, and reached the extent of a blizzard in coast districts. The snow and sleet was of the right consistency to hang to whatever object it touched, and trees and telegraph poles suffered unusually. Eleven C3'clones and nine anticyclones influenced the weather, most of them being of marked energy and n)oving rapidly. C. D. WARNER, Meteorologist. FRANK L.

In the western part of the state it was cool for the month but there was only about the average rain and snowfall. At Boston it was cooler than usual up to the 11th; from the 11th to 22nd it was quite warm with the 15th, 16th and 17th the warmest days for the month. After the 22nd it was cooler than normal with the coldest day on the 29. The month was not cold enough to make up for the former warmth and at this station the accumulated excess for the year is oSl'* or 1.6° per day above the normal. The rainfall at Boston for the month was .82 inches greater than the usual amount ; more than half the total amount came in the storm of the 27th. The deficiency for the year at Boston amounts to 9.74 inches. The snow came in full the usual amount over the state and the ground is generally well covered throughout all the cold weather, so that no field crops or roots have been injured to any ex- tent. The springs and wells have not filled up and in eastern towns there is some complaint (>f nearly dry wells. The weather was influenced by the passage of eight cyclones and seven aulicyclones. The latter were generally wide spread and their influence prevailed. The cyclones were most of them energetic and moved rapidly. That which came up across Massachusetts from the south on the 27tli was the most severe. It gave severe gales with heavy snow and rain in the east and heavy snow in the center and west. Considerable damage was done along the coast. At Amherst the temperature was slightly above normal and the precipitation a little below the average. C. D. WARNER, Meteorologist. FRANK L.

The weather for the month was intluenced by the passage eastward of nine cyclonic and the same number of anticyclonic areas. Of the former five moved to the north of New England, one passed across oar district from the west, one passed to the east and south of us and two moved up the eastern coast. The storm which passed to the north of New England on the 26th developed a secondary depression over southern New England, this in turn moving up our eastern coast and causing extremely high winds and considerable loss of life ; three men were lost from a fishing schooner near Gloucester and twelve men from three barges that were wrecked near Point Judith, R. I. The month was generally mild in eastern though colder in central and western districts. At Boston the maximum temperature was nl'^ on the 7th and the minimum 4^ on the 5tli, the 5th being the coldest of the month with a mean temperature of only 10"^. The warmest day was the i;3lh with a mean of 43°. The accumulated excess for the mouth was 107° or nearly 3.5® a day above the normal. There was an unusually large number of stormy days at this sta- tion but the precipitation for the month was nearly half an inch below the normal fall. From one to two feet of snow came during the month and except along the immediate coast the ground has been fairly well covered. The covering has been sufficient to protect all roots from cold, but the partial melting of the snow and the freezing into ice around the roots and in low places has undoubtedly done some injury. There has been no cold severe enough to injure fruit buds or trees. The water supply continues low in many towns. At Amherst the temperature was about 2° above normal and the precipitation a little above the normal ; the coldest day was on the 3d, and the greatest depth of snow fell on the 26th. C. D.

T=tra<;e. REMARKS. The mean temperature and precipitation for the month were much below normal, three-fourths of the precipitation falling during the storm of the 8th ; the same observations wei*e taken at Blue Hill Observatory showing that the storm wave extended throughout the entire state. The pressure, also, on the above date was the very lowest on record at this station. The following is furnished by the New England Weather Service : The month of February has been cold and dry. The coldest spell for the mouth and in many places the coldest and most disagree- able for years was from the '3d to lUth. The temperature has regis- tered lower than it fell at any time during the cold spell, but there was a strong northerly gale and it was continued cold. At Boston the mean temperature on the Gth was only 4° above zero, being 22^ below the normal temperature for this time of year. The snowfall was not excessive but it was badly drifted and railroad trains were delayed throughout the state and practically stalled in some west- ern counties. The ice accumulation in Boston harbor was the great- est for many years, and other harbors along the coast were almost blocked with ice for a number of days. The precipitation was very light throughout the state and at the Weather Bureau Office, Boston, it was almost 2.50 inches below the normal amount. Water supplies continue low in the mterior and northern sections. The snowfall has been slightly below the usual amount, but the ground has been exceptionally well covered and it is probable that no injury has been done roots of grass or grain. Eight cyclones and live anticlones influenced the weather in Mas- sachusetts. Of the former one passed across our district from the west, one passed across from the south, two moved up the eastern coast, three passed easterly to the north of us and lay over the lakes at the end of the month. The cyclone which came from the Mexican Gulf and passed to the north across eastern Massachusetts on the 7th and 8th, was the most severe for the month. It was very ener- getic and gave the lowest barometer reading at Boston ever recorded there. It gave sharply rising temperature and heavy rain in the southeastern part of the state on the early morning of the 8th, but snow in all central and western districts. The northeast gale which preceded the storm and the northwest one which followed were both severe and did great damage along the coast. The cold wave that followed it, while it was disagreeable was not especially severe in this section, but it carried the arctic cold far into the southern states, moving the frost and snow line almost to southern Florida.

The ground is still in an unsettled condition and there is considerable snow on the mountains and in drifts in sheltered places in the valley. The mean temperature was below normal, also the precipitation which occurred on thirteen days. A thunder storm of small intensity passed over this section the 2oth. The first blue birds of the season were seen on the 31st. The following summary is furnished by the N. PL Weather Service : The weather for the month was influenced by the passage of nine cyclonic and six anticyclonic areas. The former followed a very southerly course in their movement eastward, and were not generally extensive or severe. They gave a small amount of precipitation and their southerly movement caused prevailing westerly and northerly winds and hence a colder month than is usual. The correspondents of this Service report a cold, bleak month with rain and snowfall much below the usual amounts. There is still considerable snow in the woods and in drifts in sheltered places, and the frost is not out of the ground except along the southern coast. There rhubarb is appearing, and some plowing has been done, and peas and potatoes put in. Though the season is considered late, the condition is not unfavorable. One correspondent in Essex county reports that all small fruits, strawberries especially, have been badly winter-killed, and a few report injury to clover by the freezing of ice water on the fields ; but generally the fields and gardens have been well covered with snow all winter, and it is thought the roots are in splendid condition. Fruit has not been injured, except peaches to a small extent during the cold spell of February 6th to 8th. Most of the snow has melted slowly by the sun and has gone into the ground where it will do much good, but generally ponds and water supplies are all unusually low for the season. The maple sugar season is very late and the prospect not encouraging. F. L. WARREN, Observer. »»i%^ (S? 5iV*?^HT^» V >liSS»%*OMS^^ V\li*t^f^, U>V%1.

The mean temperature for the week beginning the 4th was 69.5 degrees which is the high- est temperature ever recorded at this station so early in the year. On the i2th a period of cold weather set in, lasting until about the 22nd and reaching the low temperature of 29.5'^ and 30'^ on the 14th and 17tii days respectively. There were heavy frosts on the last named dates which did some damage to small fruits in this section. The temperature for the last ten days of the month was high and this with the previous warm weather raised the mean to three degrees above normal. Dry weather prevailed during the month, the precipitation being nearly two inches below normal. The following is furnished by the N. E. Weather Service : Four cyclones and four anticyclones controlled the* weather for our state for the month of May, and these although small in number brought unusual weather changes. The week ending the 12th was reported by many to be the warmest spell of weather experienced so early in the season for many years, if ever before. The crops that were in the ground made great growth, while buds and leaves came out on the tiees in a day almost. The arrangement of atmospheric pressure that brought these conditions was as usual in such weather ; a large poorly defined high pressure area spreading slowly off the middle Atlantic coast on to the ocean, and considerably lower pres- sure to the north, but with no well delined storm within the range of observation. The air moved very sluggishly and brouglit heat and moisture from the south, while the general absence of clouds allowed the heat from the sun to reach the ground and crops freely. The storm of the 12th was the first well defined for the month, and fol- lowing this was a marked cold-wave in only a slight ridge of high atmospheric pressure. It gave general frosts on the morning of the 14th, though clouds prevented much damage on the 13th. Another storm moved quickly along, passing to the south of New England and up the coast on the 14th and 1.5th, and was in turn followed by another wave of colder weather and frosts on the 17th. In these frosts considerable damage resulted to grapes, and small fruits, but it is not thought tliat apple or other large fruits were injured to any marked extent. Cranberry bogs that could not be fiowed were badly injured. Another warm wave at the close of the month makes this May considerable warmer than usual. At Boston the excess in tempera- ture averaged over 4 degrees a day. There was plenty of precipita- tion in the extreme southeastern districts, but in the center and west it is too dry foi- the best growth of grass and field and garden crops. F. L. WARREN, Observer.

T=trace. REMARKS. The weather for June was characterized by higher temperature than usual for this month, the average being about 3 degrees above normal, and by small amount of rain, the precipitation being nearly an inch below normal. Quite heavy rains occurred during the first six days, then commenced a hot, dry spell of weather which lasted until the last week of the month when much rain fell. During the afternoon of the 29th, a thunder storm of extreme intensity passed over this section, the lightning striking in many places and doing considerable damage to buildings. The following is furnished by the N. E. Weather Service : The weather for the month of June in Massachusetts was generally slightly warmer than usual and it was drier except in local districts where heavy thunderstorms prevailed. At Boston from a trace to .15 inch of rain fell on each of the first six days, but after the 6th no appreciable amount was recorded at the Weather Bureau office there, until the 25th. Nearly one and one-half inches fell from that date to the end of the mouth but the total for the mouth did not equal the normal by 1.58 inches. The deficiency for the six mouths end- ing June 30th at this station is 6.98 inches. In more northern dis- tricts the thunderstorm on the 28th was heavier and more good was done by the rain. At Groton, 2.74 inches came on that date, while the total for the month there was 4.76 inches. Grass especially has suffered for want of rain, and on old upland fields it has matured so fast that it has been necessary to begin cutting. Part of the injury on these fields, however, was done by the extreme drought of last year. Meadows are better and have been greatly benefitted by the rains of the last of the month. The temperature at Bostou was generally below the normal during the rainy weather, and above when clear auticyclonic weather pre- vailed. For the month it averaged there slightly less than one degree a day warmer than usual. There were four cyclonic and five auticyclonic areas influencing this state during the month, but the former especially were of indefinite area and slight energy. F. L. WARREN, Observer.

T=trace. REMARKS. The month of July has been imusual in the general lack of hot summer weather and small amount of sunshine, although the mean temperature has been about normal. The wind has been very variable, not blowing long at a time from any quarter, and so caus- ing frequent changes in temperature. The conditions are undoubt- edly due to the want of marked barometric areas or conditions. Eight cyclonic and four anticyclouic areas influenced the weather ^ during the mouth, but all of them except the last two cyclones were J of slight energy and indefinite area. The barometric changes were neither large nor rapid, but frequently the place that would be tilled by a comparatively high pressue area at one observation would have a comparatively low pressure covering it at the next. The M cyclone of the 27th — 28th was energetic and well defined and gave ' heavy rain, high wind and severe local storms. The precipitation has been below normal and especially light in southeastern sections, but even there enough has fallen to keep crops growing fast. Partly made hay has been injured to considerable extent by the frequent rains, but pastures have continued unusually green, and the grass of fields is starting up fast after the scythe. The season has been one of the best for forage crops, but the moist weather has given an impetus to fungi ; potatoes, grapes, cherries, peaches, etc., have been slightly injured. F. L.

With a smaller range of barometric pressures than has thus far been recorded for September at this station, it has given us the greatest number of hours of sunshine, the maximum and the highest mean daily temperatures, the greatest range and the greatest and least mean daily range of temperatures for September and the woi'st hurricane on record at this station. Not only did September make a new record of " highest tempera- ture " for itself, but it also established the maximum temperature for the year recorded here, the thermometers registering 9 1'* and 97° in the ground and observatory shelters respectively on the 23d instant. The storm of the 11th instant was the most notable feature of the month. \Vith a normal though slightly falling barometer, tempera- ture of S-f^, wind from the south-south-east, and a clear sky, sud- denly, about three o'clock in the afternoon, there came from the northeast a hurricane accompanied with blinding sheets of rain, bright flashes of lightning, and terrific gusts of wind, reenforced by a steady gale and mass of hail. For nearly twenty minutes the storm fairly raged, but had spent itself at the end of half an hour when the wind ceased and the sun shone brightly. The gale had left a record of a velocity of 93 miles per hour, a sudden fall of 14*^ in temperature, from 84^ to TO'^, and an inch and third of rain, fully an inch and a quarter of which must have fallen in twenty minutes. Several hailstones were found by one observer measuring two inches in length, and one at least one and one-quarter inches in diameter. Many trees were nplit and broken by the storm, standing corn was blown down, and fruit very generally blown from the trees and vines. Much glass v,as broken in the plant houses and considerable slate was stripped from the roof of the JMassachu- setts Agricultural College Chapel. Other noteworthy features of the month were the extreme heat of the 21st, 22(1 and 23d instants, (95°, 9.')^, and 97"" in the ground shelter) and tlie heavy rain of the 2'J-3 )th instant.

T=trace. REMARKS. The Boston Office of the Weather Bureau reports that : — " Eight ej^elouic and the same number of anti- cyclonic areas con- trolled the weather for Massachusetts during the month of October. Six of the cyclones passed easterly to the north of us, one passed up our eastern coast well out to sea, and one moved from the Lakes to the south of us and then up the coast. The last named was the most notable of the month, as it gave the heaviest continuous rain in eastern INIassachusetts, that we have record of. At Boston the rain began at 1.55 p. m. of the 12th, and ended at 4.30 a. m. of the 14th, the amount of rainfall being 5.64 inches. 4.85 inches fell from 8 p. M, of the 12th to 8 p. m. of the 13th. At Nantucket, Mass., and at Portland, Me., the rainfall was light during the storm. * * * * The following amounts are reported by the Boston Water Works : Chestnut Hill, 7.55 inches ; West Medford, 7.42 ; Ashland, 7.50 ; Lake Cochituate, 6.95; Cordaville, 7.60; Framiugham, 8.49. The fall at Wakefield was 6.60 inches. Considerable damage was done to the streets, and cellars were flooded. All danger from a water famine for the present is past in this part of the State." At this station, however, the rainfall for the month of October has been about normal. As in the eastern part of the State the storm of the 12th and 13th instants was the worst storm of the month, result- ing hei'e in an unusually high record of wind for the month (5029 miles) and a large rainfall, (about 2.6 inches between 11 a. m. of the 12th and midnight of the 13th instant), though nothing like the phenomenal amounts recorded near the coast. The month has been considerably cooler than usual, the mean daily temperatui-e being about 3*^ below our average for October, while the highest and lowest mean daily temperatures have also been slightly below the average. A trace of snow, the first of the season, fell on the 20th instant, and the hills lying to the west of Amherst were capped with snow on the morning of November first.

T=trace. REMARKS. The month of November has been one of marked barometric activ- ity and thi)ugh the areas of barometric depression have predominated, accompanied h}' a large percentage of clondiness (62%), high rela- tive humidity (80.5%) and heavy rainfall (5.36"; the mean barom- eter (30.187") and range of pressure (1.45") have been unusually high for this station. These fluctuations in the atmospheric pressure have in general been very marked and sudden. Between Oct. 30th, 10 a. m. and Nov. 1st, 3 A. M., 17 hours, the barometer fell .94 of an inch ; from 12 p. M. Nov. 21st, to 9 A. M. 22d, 33 hours, it rose 1.34 inches or 1.05 inches from midnight to midnight on the 21st; and .8 of an inch from 7 : 30 p. m. on the 26th to 12 : 30 m. on the 27th, 17 hours. "There were only six anticyclones spreading near enough to us to influence the weather, while nine ■ cyclones gave us part of their clouds and moisture. Of the latter five pass«^d easterly to the north of us and three moved up our eastern coast. Three of those that passed to the north came from the southwest, and moved with in- creasing energy up the Mississippi and Ohio valleys to the Lakes drawing in large volumes of warm moisture-laden air from the Southern latitudes, and so aiding in increasing our precipitation and making the temperature for the mouth average from two to three degrees a day higher than usual. Two of these storms passed by to the north of us at about midnight and were then followed by a shaip cold wave with rising barometer." The mean temperature (41.1") for the month has been about two degrees above tlie normal. The wind storms have in general been moderate and of short duration. Those accompanying the storms of the 21st and 26th instants,— so serious in the West, — were however more severe, regis- tering velocities of 67 and 58 miles respectively at their maxima. An unusually heavy fog was observed on the evening of the 19th instant. LEONARD METCALF, Acting Meteorologist. CHARLES A. KING, Observer. JAMES L. BARTLETT, Asst. Observer.

Three of the cyclones passed easterly to the north of us, two across our district from west to east ; two moved up our eastern coast well out to sea, and one passed easterly to the south of us then up the seaboard. The low pressure areas predominated. The two storms that passed up the coast were not severe over the greater part of Massachusetts, but on the Cape very high gales prevailed, and considerable damage was done to vessels outside on the ocean. The storm that passed across New England on the 2d, and the one that passed from the Lakes to the south of us and then up the coast on the 5th-6th gave considerable snow. But the last part of the month has been so unusually warm that the snow has all disappeared, the frost is mostly out of the ground, and one sees everywhere farmers working on their land as in the early fall. The two storms that moved northeasterly down the St. Lawrence valley on the night of the 26th-27thand 30th-31st, respectively, increased rapidly in energy, and gave heavy rains and tremendous winds over our entire district. Fences were wrecked, out-buildiugs blown over or unroofed, and windows blown in." (J. Warren Smith, Director N. E. Weather Service.) At Amherst too, the storms of the 27th and 31st instants were notable ones. During the former the wind attained a maximum velocity of 69 miles per hour, while the latter if not quite so intense (62 miles per hour) was more prolonged, and fittingly closed a mouth of unusually high record of wind (5506 miles) with the maximum daily movement for the year, — 454 miles. The range of barometric activity during the month is also worthy of note, as it gives us a new record for maximum range of barometer for December: — from the very high pressure of 30.55 inches at 10 A. M. on the morning of the ITtli instant, to the unusually low pres- sure of 28.77 inches at 5 a. m. during the storm of the 31st instant, a range of 1.78 inches against 1.725, the highest previous December record. The mean daily temperature for the month was 32° F., nearl}' two degrees warmer than the average, and the normal temperature con- ditions for the month were quite reversed, the mean daily tempera- ture for the first half of it, from the first to the 18th instants, except- ing the 2d, being below, while the lemainder was considerably above the normal tem|ierature. The marked contrast between these con- ditions is strikingly illustrated by the facts that on December 18th several inches of snow lay on the ground and ice from eight to ten inches thick was cut from the pond at the Massachusetts Agricultural College, while at the close of the month all traces of snow had dis- appeared and the ground was soft and muddy.

T=trace. REMARKS. The past month has been an unusally pleasant one for this season of the 3'ear. The atmospheric pressure has been quite constant and very high, the range of pressure being exceedingly small. " The storms, travelling generally to the north of us, moved slowly during the latter part of the month, while the earlier ones moved with greater rapidity and were followed more quickly by cold waves. The most notable of these that of the 5th. — 7th. insts. in New England developed in the Norlhwtbt on the Ist.iust.and spread generally and uniformly over the entire country, as predicted by the Weather Bureau twenty hours before its arrival. As the ground was entirely bare during this cold wave it is thought considerable injury has resulted to grass and grain roots and to the roots of fruit trees, although not so much as would have been caused had it occurred later in the season." (Abstracted from J. Warren Smith's January report., — N. E. Weather Bureau. The mean temperature has been about four degrees below the normal. The first three days of the mouth were very warm, the 4th. -18th. insts. decidedly below the normal, while from that time to the end of the month the temperature, with a few minor exceptions has been above the normal. The 6th. inst. with its minimum temperature of twelve degrees below zero ( — 12°) and mean temperature eight- tenths of a degree below zero ( — 0.8°) is worthy of special note. The precipitation has been exceedingly small, but 1.07 inches of water, and while the meadows and hills have been covered with snow since the 9th. inst. there have been but five days of sleighing during the month.

T=trace. t early. REMARKS. The past month has been one of climatic extremes, giving us a taste of both the biting cold of mid-winter and the mild, soft days of spring. The first eleven days of the month with the exception of the 3rd. instant, were considerably above the average temperature for Febru- ary, the following eleven days, excepting the 14th. and loth, instants decidedly below, — reaching a minimum 14° below zero, in the ground shelter, and a mean for the day 1.7° below zero, on the 17th. instant. After this time, (i. e. the 22ud. inst.) the tem[)erature was more variable, but the month closed with springlike days, a heavy rain, and the ground clear of snow and free from frost. The month has been exceedingly windy ; the mean barometric pressure unusually low ; the relative humidity of the atmosphere large ; and the precipitation above the average, though the snowfall has been very light. The worst storm of the month was the hurricane of the 6-7th. inst., during which, at its maximum, the wind blew at the rate of 60 miles an hour for over an hour, as indicated by the anemometer. The barometer fell exceedingly rapidly just before and during this storm, in all 1.23 inches in 24 hours, on the 6th. inst., from 0 a. m. to 12 p. M., or 1 .0 inch in 11 hours, between 7 a. m. and 6 p. m. LEONARD METCALF, Acting Meteorologist. C. A. KING, Observer.

The mean temperature has been considerably below our normal temperature, — about five degrees,— that of the 1st, 19th, 22d, 2Gth, 30th, and 31st instants only, being above the normal. The range of barometric pressures has been unusually large, varying from 30.28 inches to 28.77 inches of mercury. The total wind movement for the month was the largest on record here for March, 8182 miles; the greatest daily movement being 620 miles on the 4th instant. The snowfall on the 15th-16th instants was the heaviest of the winter ; the total for the month being the same as that for March, 1890, seventeen inches. The total precipitation was unusually heavy, 6.11 inches, and considerable damage was done to the roads and fields by erosion, by the storms of Feb. 29 to March 3, March 19 to 20th, and March 29 to 30th. '' Seven cyclonic and six anticyclonic areas influenced our weather during the month. Of the former three passed easterly to the north of us, one moved across our district from the south, one from the west, and two moved up the Eastern coast. The high pressure areas were generally energetic and were accompanied by low temperatures. The heavy rains of Feb. 29 to March 3d occurred in a storm which moved from the southwest over eastern New York, across southern New England from west to east, on the first, and then passed slowly along our coast, increasing in energy. Roads were badlj' washed aud much damage was done along river valleys by high water and broken ice. It is feared that in some sections the frequent freezing and tliawing of the ground has worked some injury to clover and other grasses." (J. Warren Smith, New England Weather Bureau.)

The amount of sunshine too has been unusually large, being 15% in excess of the normal for April, and the last half of the month has been further characterized by hot days and cool nights. The first eleven days of April were from 4^ to 20° colder than normal and the season was decidedly backward. Then followed ten days of very warm weather in the course of which the excess of tem- perature reached a maximum of '2()^ above nornial on the 16th inst. and during which vegetation was given a good start and made rapid progress. While the temperature during the remainder of the month, with the exception of the '2'M and 25th insts. was also above the mean, the season since then has advanced more slowly.

T=trace. REMARKS. The most noteworthy features of the past month were the deficiency of rainfall and the abundance of sunshine. The total precipitation for the month was but 2.58 inches, of which less than one quarter of an inch fell before .the 26th instant; the amount of sunshine recorded was 65%. The atmospheric pressure has been generally high and steady with a small range for the month. The mean daily temperature was about 4^ above the normal but the nights have been generally cool and comfortable. The hottest day, the 10th inst., whose mean temperature was Sl*^, gave us a new maximum for May, 94.3°. "Eight cyclonic and seven anticyclonic areas influenced the weather in New England during the month of May. During the first two-thirds of the month, these areas moved with little velocity or energy. The low pressure areas especially were poorly defined and gave only a moderate amount of clouds and very little rainfall in any section of our district. During the last week the cyclonic storms have been more energetic and have generated severe local storms. None of them, however, have been so severe in this section as in the Central States, as the storms have decreased in energy as they crossed the Lake region." — N. E. Weather Bureau. The conditions for f ^rm work have been generally good except in localities where the ground is naturally very dry. Planting is fin- ished except in occasional late corn fields for the silo. Tobacco set- ting from hot beds was begun last week and is still in progress. Seeds have germinated well for the most part and the recent rains have given everything a good start. Grass-land, however, has felt the drought severely and the hay crop must inevitably suffer. Violent winds, coupled with the extreme dryness, have done con- siderable damage. That of the 18th inst. was much the most serious one, shrivelling the tender leaves on many maples and other trees and shrubs, and doing much damage to the fine alluvial soils of the Connecticut valley in all exposed localities. It swept the surface soil off in many cases for a depth of upwards of three-quarters of an inch and laid bare or swept away the plant roots. The onion crop suffered most, though the injury was of a local character, confined to knolls and other exposed situations. Professor Brooks mentions among others one field of four acres in Sunderland meadows from which every vestige of the crop (onions) was swept away and the surface left seemingly as hard as a board floor. Insect pests have flourished in the dry weather and have done considerable damage. LEONARD METCALF, Acting Meteorologist. JAMES L. BARTLETT, Observer.

T=trace. REMARKS. The past mouth presents few features of particular interest. It has been a normal June, though cool aud dry in this vicinity. While the amount of sunshine was in excess of the normal, the nights were generally cool and the mean temperature was more than two degrees below normal. There were some hot days during the month but the heat was neither excessive uor of long duration. The rainfall was deficient by nearly one inch. The low temperature has had the effect of retarding the growth of tobacco, corn, squash, tomatoes, melons, etc. on, all soils except those naturally warm. The weather was almost phenomenally fav- orable for tobacco setting during the early part of the month. The strawberry crop has been rather disappointing and raspberries are doing poorly, but the blackberries and currants promise well. Hay- ing is well under way and the crop is generally light on all except the very fertile and moisture retentive soils, as was anticipated. The cut worms have been very numerous and troublesome, seri- ously thinning the fields of onions and tobacco as well as tender gar- den truck. The elm-leaf beetles are very abundant and doing much damage, as did the canker worms during the early part of the month. LEONARD METCALF, Acting Meteorologist. JAMES L. BARTLETT, Observer.

The month was somewhat more windy and hotter than usual ; but while the mean temperature was nearly two degrees above normal the rainfall was abundant and well distributed, so the crops are in excellent condition and pastures and lawns are unusually green for the season. The hay crop, which has been harvested, proved heavier than was anticipated early in the season, in consequence of the abundant rain- fall of the month. There is moreover an excellent prospect of a good crop of rowen in fields from which the hay was cut early in the season, except iu the few cases where the army worm fed upon the new growth as it started. Tobacco has been topped in most fields and is growing rapidly. It will be noticed that certain changes have been made in the bul- letin for this month. The temperature readings in the observatory tower will not be published henceforth as it is believed that the vari- ation in the tower and ground readings is, at times, as much due to difference in exposure as to difference in elevation. All temperature observations, therefore, which are published, are taken in the old ground-shelter, which stands on the side of the campus, several hun- dred feet from any buildings or large trees. The mean daily tem- perature, as figured from the maximum and minimum temperature readings, is also given, as is the daily mean sensible temperature, (being the mean of the 7 a.'m., 2 p. m., and 9 p. m. wet-bulb ther- mometer readings) .

" August has been a very favorable month from an agricultural point of view. It opened with plenty of heat, sunshine and mois- ture, and with all crops pushing ahead fast, except the potato vines which were considerably blighted in the south by the excessive moisture and humidity. Unusually hot and sultry weather continued over the second week of the month so that cabbages and cranberries were considerably damaged, though corn, tobacco, and similar crops made very rapid growth." — N. E. Weallicr Bureau. This hot wave, from the 3rd to the 13th instant was the most trying that we have had, since July 1892, and was much more protracted than the latter. The long lists of deaths, resulting from the heat, in our large cities, published daily in the newspapers, dur- ing the latter part of this hot spell, bore witness to its intensity. The last half of the month has been considerably cooler and drier, with plenty of sunshine. Corn has continued to grow well and the tobacco crop, now well under cover, is a fine one, notably so, owing to the very favorable season and absence of violent storms. Pasture lands are in excellent condition and a good crop of rowen has been cut from many of the earlier fields. LEONARD METCALF, Meteorologist. JAMES L. BARTLETT, Observer.

T=trace. REMARKS. The New England Weather Bureau reports, for the past month, that "rain has been frequent and excessive in all districts. Crops have ripened pretty well, but the weather has been unfavorable for curing corn and grain and for harvesting the second crop. The ground is well filled with water at the end of the month and wells and springs are filling up fast. The weather has been exceptionally favorable for the growth of late forage crops and for pastures and newly seeded fields. Stock will come to the barns in unusually good condition from most pastures. The conditions have been unfavorable however for potatoes, and rust and decay have increased over most of the state. Fruit has been shaken from the trees com- paratively little by wind storms. Local rain and thunderstorms have been as frequent and damag- ing as during any month this season. They were especially severe on the 5th— 6th, 9th— 10th, and 19th instants. Tobacco was secured remarkably from damage by the weather and is reported to be curing well." At Amherst the precipitation was about an inch and a half in excess of the normal amount, and the mean temperature for the month was about two degrees below normal. The first frost of the season in the ground shelter was on the 24th instant, when ihe tem- perature fell to 31° F., and a light frost was noted in the lowlands on the 21st instant. Neither of them however did serious damage. The corn crop, which matured late, is reported as abundant and good, and rowen exceptionally good. The onion crop is poor and light owing to the early winds and blight, and potatoes are suffering from rot and rust to some extent. Apples and grapes are both abundant and fine.

October, visually the most charming month of the fall in the coun- try, has been a great disappointment in this vicinity this year. Instead of the fine display of autumn foliage to which everything seemed to point earlier in the season, we have had a cheerless and stormy month with very few of the customary bright and bracing autumn days. We have had but 34 '^ of the possible sunshine, the smallest amount on record for October at this station, — the lowest previous record being 42% in 1895. The mean temperature of the month was nearly 3" below normal, while the mean relative humidity was exceptionally high. In spite of the large amount of stormy weather, however, the rain- fall was an inch below normal. " A number of severe storms have passed near enough to us to give cloudy and threatening weather and some wind, but not near enough for us to get the worst part of the disturbances. The most noteworthy was the West Indies hurricane of the 12th. to 16th. This was first noted over the West Indies on the 7th. and moved slowly up the coast, well out to sea. Storm signals were ordered and displayed all along our coasts, giving ample warning of the gale. The wind reached hurricane force on our extreme eastern coast, while the center of the storm was several hundred miles out to sea." (J. Warren Smith, N. E. Weather Bureau.) The month has been generally unfavorable for fall farming opera- tions. Corn has not cured well and tobacco is reported as rotting to some extent owing to the excessive dampness. Fall seeding and grains have made an excellent catch, however, and pastures are in fine condition. LEONARD METCALF, Meteorologist. JAMES L. BARTLETT, Observer.

T=trace. REMARKS. The weather of the past month has been justly characterized as unseasonable. The mean daily temperature for the month was nearly 4.5"^ above normal, that of the first three weeks being, with four exceptions, considerably above the mean, while the last ten days witnessed the passage of two marked anticyclones which brought with them more seasonable weather. Though the precipitation shows a deficiency of nearly one inch, the mean relative humidity and percentage of cloudiness have been very high, as has the mean barometric pressure, the latter chiefly in consequence of the unusually high pressures accompanying the anti- cyclone of the 20th. to 24th. instants. The first trace of snow of the season fell on the 14th. inst. LEONARD METCALF, Meteorologist. JAMES L. BARTLETT, Observer.
